Copy, Paste, and Recent Phone Numbers in Android SMS on Lumashare

I'd like to request an improvement to the Android SMS sharing station to make sending multiple sessions to the same guest easier.

It would be very helpful if the phone number field supported copy and paste for SMS sharing. Email sharing already supports copy and paste, but for some reason SMS doesn't. (Can copy and paste in both on IOS as well)

Better yet, it would be great if the app could keep a dropdown list of recent phone numbers used in the sharing station. That would make it much faster to select repeat guests.
