Just put "testingcheatsenabled true" into the cheat box. Shift click the desired sim, and on the pie menu, the option "add to active family" should be there. F.Y.I. you bring up the cheat box by pressing shift, "C", and ctrl at the same time.

Ok, thanks for clearing up the confusion.

Thank you for showing me the link to the 2.4 version, but I asked for the 2.5 version. The thread clearly states that AM has been updated to the 2.5 version, but here is what I saw.
OFFICIAL 1.10/2.5/3.1 UPDATE
Updated for latest patch.
Fixed issue with sims spawning with an everyday uniform in every category.

So, where is the update? 

Where's the link to the 2.5 version of awesomemod? The awesomemod thread says that it has been updated to 2.5, but the link only contains the 1.9, 2.4, and 3.0 version.
