Mapping bottom tab bar to multiple pages

With the bottom tab bar, there is an option to use "Multiple Pages". If that is chosen, you have one URL Path entry field and an option to include subdomains.

If I want a certain menu to be used on multiple URLs, is there a way to map that? I'm not sure if the Custom option will let you comma separate expressions. I'm looking to use one tab bar on multiple pages for example:

https://mysite.com/here

https://mysite.com/heretoo

Second menu here:
https://mysite.com/secondmenu

So rather than building one menu for the first two URL's, I'd like to combine that (as I have several of these).
I can't use the subdomain option as I have menus for various areas in the domain.

Thanks.
