Adding actors to custom units

[Froggy707]

How do I add an actor to a custom unit, to clarify I mean when I'm in Data units, I click my copied barracks, I want to add a diffrent portrait or a icon at the bottom where it lists the already present ones, I noticed when you copy a unit it doesn't copy EVERYTHING, anyone able to help?

Avoid using Copy/Paste with things like units that have many links to other data, use Duplicate Object instead and check the boxes with actors/effect/etc. of the fields you want to change.

Thank you, I duplicated and it worked perfectly.
Edit: Actually I did it and weird shit happend, when I start the game, the default built barracks is a Barracks Copy, I mean like when I build a Barracks with my SCV it changes the orignal built barracks to my duplicated one.
