Windows 10: How can I copy an existing Outlook contact list to new contact list under a different name?

I have a large contact list hundreds of contacts that I want to copy to a 2nd contact list which I can then remove a few contacts and so have two contact lists that are slightly different from each other without having to create the 2nd contact list from scratch. I am using Outlook both web and application versions on Windows 10.

Only suggest people in my contact list, outlook windows 10 app

FYI:

 

Yahoo Email Contacts List

At work I have a rather large list of contacts, sometimes I have multiple email addresses within one single contact. For example, lets say I have a contact "Bob", within that contact I have L: emailaddress1@techpowerupisawesome.com and L: emailaddress2@techpowerupisawesome.com. When I begin a new email, if I type "Bob", both of these addresses will appear, but I can only select one. I'd like to select both without having to retype Bob to make the list appear again to click the other.

I'm aware you can click the "To:" button to make the list of contacts appear, but you need to scroll down and find your contact, then shift click to select them all. Scrolling around can be troublesome with the amount of contacts I have. I'm not really interested in making groups for various reasons.

So is what I'm trying to do possible or am I asking too much?
