Even better news Kevin! Now that Premiere can create subclips without hard in/out points, it's a (big) step closer to being all it can be: the best NLE available!
Hopefully that checkbox remembers the last state used, so you don't have to uncheck it everytime you create a subclip. Do you know the answer to that? Outstanding news!
BTW, I'm guessing you knew that this feature is coming up but never hinted at it in the thread I posted about subclips (as per NDA agreements). Very well played. 
hehehe
