Playtime: Playback position of a clip follows other already playing clips' playback position

[HeikoBloemers]

hello!

In case my request has already been requested in another thread, please let me know so I can upvote that one and continue discussion there. I have used the search function and haven't found anything similar so here goes:

Imagine I have recorded 3 clips, all recorded in row1 of 3 different columns (col1, col2, col3).
all 3 clips are each 4 bars long.
the 2 clips in col1 and col2 are currently playing back at the same time.
now, upon starting playback of the clip in col3 it will start playing back from its beginning (respecting its start timing setting of course).
however, I would like to be able to have it "pick-up" the other clips' playback position and join them (again respecting its start timing setting of course).
So, I guess what I am requesting is a new setting (could be of similar nature as "start timing"; as in: can be set for matrix scenes as well as individual columns. or even could be set per individual cell/clip itself) called something like "playback position" with (at least the three, cannot think of more right now) options "start (default)", "relative position" and "absolute position".
"start (default)": that case is how playtime² is behaving already
"absolute position": could be defined in either beats/bars
"relative position" (that's the case I am requesting): sets the starting playback position relative to the other already playing clips' current playback position.

regarding "relative position": I am aware that in certain (edge) cases this feature will need thinking about, for example what if the two playing clips in my example do not have the same length but rather clip1 is 4 bars long and clip2 8 bars. I guess relative would mean an "average" of the two playing clips, so e.g.: if both clips started playing together the relative position would be at 6 bars. but if the third clip is actually not even 6 bars long, so what would happen in this case? I am happy to hear your thoughts on this.
I am focusing my request mainly on the fact that all playing clips are of the same length/have the same duration.

Thanks for your reading and your consideration.
Warm wishes,
Heiko
