When you work in the TM view, you can make, use and name filters. You also can export them for later use (import). Those two buttons are present.
When you export a TM, you can also make a filter there. Unfortunately you cannot import (nor export) filters you made earlier. You have to make your filter(s) all over again.
It should be easy to add those two buttons to the Export Options? They already exist in the program code, don't they?
Thanks
