Tags in Maya - Importing

Is there a way to add a ‘Tag’ in Maya and have it imported to unit? or is there anyway way to assign them in Maya?

I am guessing it all has to be done in Unity, but you never know.

To my knowledge there’s no way to do that. It may be possible if you write a clever import script that when importing ‘reads’ the Maya tags and creates/assigns corresponding Unity tags, but in most cases it’s probably easier to just do it in Unity I assume.
