Windows 10 - Change Display Numbers / Identity

I can get to the display setting where I can re-order displays:





But is it possible to actually re-number them as well?

The reason simply re-ordering doesn't fit my use case, is because other applications, like Skype, will use the original numbers and locations, which leads to some counterintuitive selections





All of these threads just suggest using display settings to shuffle monitors around:

How does one change their monitor's "Identity Number"?

I've been have problems that seems to be tied to Monitor Identity Numbers that fully ignores the settings for which monitor is set to main monitor. I have looked up for days through "Microsoft Support" and through the community in here
(and in other places), and came to the conclusion that the majority of the answers I find are just ignorant people of what is actually being asked.

My current monitors I have are as shown below, with their "Identity Numbers" and with the addition of stating which one is marked "Make This My Main Display":

M422i-B1 (TV screen)

Resolution: 1920 x 1080

Monitor Identity Number: 1

Acer LCD Monitor P201W (Computer Screen) "Main Display"

Resolution: 1680 x 1050

Monitor Identity Number: 2

In the beginning prior to set-up, their "Identity Numbers" were originally swapped as the Acer was the original "Identity Number 1" screen, but now every time plug in a second screen (or monitor), it lists Acer as "#2". Despite the Acer Monitor is
set to be the "Main Dispaly", almost all applications are opened up on my tv screen. The only way I can seem to remedy this is by moving them to the Acer Monitor and close the app on that one, but this would require to do upon right after logging into my pc. I
have seen suggestions of using 3rd party applications for "Window Settings", only to be failed by the many versus the few stating that Windows OS supersede those settings in terms of "Monitor Identity".

To state, a lot of people seem to assume that the "Monitor's Identity Number" is not important, but in terms of experience (that seems many has shared), that this is actually relevant to the system regardless of the display settings
for what is marked as the "Main Display". I do hope I get a proper answer for a question that has been asked for 10 years that seems to have not been dodged and/or misunderstood.
To add, I do not seek for the answer of going through display setting and moving the monitors around as that too is, painfully in truth, a sign of ignorance.

I do apologize for typing up a long explanation, but sometimes, one needs to be detailed about the situation to show not just the big picture, but also the small ones the create the larger problem.
