I'm always in need of slicing adjacent surfaces, sometimes it's for slicing all adjacent surfaces wrapped all around a model, sometimes ...

So I usually insert a vertex on each edge and then slice the surfaces.
It sometimes takes a lot of time.

I was thinking that maybe you could add an option to the divide surface feature :

1 - divide the same as today (widths and heights)
2 - divide only the widths
3 - divide only the heights
