Putting units in a group when they exit fac

Hello.

I wanted to know if it was possible to put automatically some units in groups when they are built.

Example :

Is it possible to force a Fac to add Mistrals in group 1 and Hunters in group 2 ?

Also : Is it possible to add a unit to more than one group ?


Apparently, some people are very good at using simultaneously, say, Seawolves, Sirens, and Seawolves+Sirens. Make me very jealous.

to add to this, standard auto group setting is, that they get added to the group AFTER following the factory command if one exits, but there is a setting where they get added to the group immediately after production.
