Can I choose what firmware version I want?

I’m currently on 1.06, and I wouldn’t mind going to 1.07 on my P1S, as long as my Panda touch is still supported (BTT says it is). From what I’ve read, I have to already be on 1.07 to do an offline update. At this point, I guess I’m stuck, unless someone knows some super secret squirrel stuff.
