I don't really know if this is possible,
but what if there was a way to use the stage editor to make
custom stages as wide, as a at-least a small subspace level
by taking two custom stages and putting in a comment like
finaldst p1, finaldst p2 finaldst p3 for each of them
it would conjoin them at the x axis from left to right according to the assigned number and title
to make extra wide stages!
speaking purely conceptually could a code like this
ever happen?
here is a example, I just souped up a picture I found on google images.
