Match Offset without MIX area

Hello,
Is there any way how to match offset without mix area?

If I match offset with this layout, i got z=5,


but if i mix second clip into first and than match offset, it calculate z=4 becaus it does not start from end of first clip but from start of mix.



Sometimes it is good but in my example i need offset z=5, so i must sort clips as in the first picture, match offsets and than create MIX.

From another observation, the offset point position is best somwhere in the middle of MIX, so maybe add something like offset adjustment from 0 to 100% or just add another keyframe in the middle of mix.



And somting like "automatic match offset to prev/next clip with/without mix area" will be good flow improvement.
