align both bars and timecode to zero

You’re all right, I AM a bit confused.

I’m not so much concerned with offset at the beginning of the project (I’d rather have lots of available space prior to the starting point). I just want WHEREVER in the timeline I start the project to be zero (or 1) for BOTH bar+beats and time displays.

In other words, I’d like to be able, at any given point along the timeline, to switch between time & bars+beats display and know how far I am (what bar, how many min:seconds) into the track.

So, for example, I’d like to be able to set 00.00.00.00 at say 10 minutes offset from the beginning of the project (so all times prior to that point are negative), and make that same point the starting beat (whether 0.1.1.0 or 1.1.1.0 I don’t really care. OR the other way around - can I set my cursor at 1.1.1.0 and make the time display say 00.00.00.00 at that position? (and STAY that way if I change the tempo?)

Does this make sense?
