Feature Request for REACH: add button that copies single-mode GPS coords into base-mode input fields

It would be nice to have a button that copies the GPS coordinates picked up in single-mode on the Rover pane into the base-mode on the Base pane.

I suppose this would require that the coords be written to a temp pseudo-config file when switching out of the Rover pane and then re-read into the Base pane.

This definitely is a desirable addition and it is on our todo list.
