Forging seems super dangerous

Unless I'm missing something, it seems like it would be really really easy to accidentally forge the wrong units. I didn't see a way to lock units to prevent accidental tampering, and when you're in the forging interface and you select a unit to be forged, you just get a really faint white box around them with no confirmation window. I mean obviously the correct thing to do is just to be super careful and triple check before I forge anything, but am I missing some way to protect my important units that I'm just not seeing?

Yeah, some kind of a marking system would be very good.
