Game Messages to Triggering player.. Possible?

I need a way to say this in trigger format.. is it possible? I sure cant find the right stuff.

Event: Unit Enters Region
Condition:
Action: Display for 10 seconds the text "yaydyadya" for owner of entering unit.

I CANNOT figure out how to do that.. and it would make my life so much easier lol.

Use the Convert Player to unit group Function

Event: Unit Enters Region
Condition:
Action: Display for 10 seconds the text "yaydyadya" for (Convert (owner of entering unit.) to player Group)

UMSWE adds this feature into the WE(As Game - Text Message to Player which has the ability to allow for owner of entering unit) so perhaps you may want to download that in the downloads section of this site. If for some reason you're dead set against downloading UMSWE you could add owner of entering unit to a player group via covert to player group and then have it show the text to that player group(since the owner of the entering unit would be the only person in it, it'd only show the text to him/her).

EDIT : Beaten to it :P.

Ah, thank you both.. i just never noticed that little nifty action down there XD
