First back up your GSAK databases in case anything goes wrong.
Create a new database for the caches you want to send to Cachemate: Database > New... Select an appropriate name for the new database.
Then do the following with each of your 3 existing databases in turn:
Check the User Flag for each of the caches you want to move to the new database. Then choose Search > User flag set
You should now only see the caches you've set User Flags for.
Choose Database > Move/Copy waypoints. In the dialog box select your new database from the dropdown list. Click on Go.
I hope that helps.
Edited to add: I'm using GSAK v6, but I imagine it's similar if not the same in v7.
