Is there a way to copy a custom unit from one map to another?

I wanted to import a custom unit from one map into another so I wouldn't have to go through and re-create them is this possible?

Ya can using the normal import/export feature in the unit editor, it just doesn't _appear_ the units have been imported. If you import them, then save, then close the map and reopen it, they'll be there.

Can't you just CTRL-C them, then go to your map, and CTRL-V?

Thank you I never even thought to look there! :)
