How do you choose panic vs MC when controlling an alien?

[Countdown]

Maybe a dumb question, but when you are in control of an alien (either sectoid or ethereal) and are using their mind attacks (via the grey ish "psi" button in the top right), how do you designate whether you want to use their panic attack or mind control?

PS - Also is there a way to alter how much improvement you get from the psi lab each month? I know you can alter how many soldiers.

you don't.

as for psi training, it works on a scale according to the caps.
