Windows 10: Polytonic Greek keyboard - suggestion for improvement

I suggest MS add lunate sigma U+03f2 to the Polytonic Greek keyboard. It has an earlier history at least 4thC BCE than the forms of sigma final and other that MS currently includes earliest 1stC CE, but probably only really from 8thC CE.

Greek polytonic keyboard

There is currently no Greek polytonic keyboard available on Windows, for use in typing ancient Greek, only non-polytonic (modern) Greek. I see this question was asked in 2017, but it still is not available. Are there no plans to add it?

 

Polytonic Greek

Step 1: Set the Language.

Click the Start button, then type “Region and Language,” and press Enter.

Under Languages, click Add a language, then type Greek in the search box.

Select Greek.

After that, select Greek under Languages and click Set as default.

Step 2: Add keyboard.

Under Languages, choose Greek and click Option

Under Keyboards, click Add a keyboard.

Then, choose Greek Polytonic.

After you change the language and add the keyboard, you need to Press Windows key + Spacebar (without releasing the Window key, press the spacebar) to switch between installed keyboards (choose Greek Polytonic).

Polytonic Greek

Yeah, but as I literally said above, I have done this already. Language settings and keyboard are set to polytonic Greek. I just can't see how to manage certain combinations of accent+breathing mark which are absolutely standard for Polytonic Greek. But
when I open the onscreen keyboard it only shows the option of combining a rough breathing mark with an acute accent. This is just bizarre.
