Yes.  You can easily do this in the GNOME Control center, just try it.
Click "Manual", and then the "+" will allow adding multiple IPv4 (or
IPv6) addresses to a single interface.

As Tomaz mentions that's the legacy way; what NM writes into the
network-scripts when you do the above is the modern way.

The new nmcli will help here...could possibly land in a post-release
update.  But if you look at what NM writes for the above you can see how
it works:
