Sorry if this title is confusing, but what I'm looking for is pretty simple in concept.
Essentially, I'm making use of loop cut & slide to slice up long objects, and then using a Curve modifier to bend them. However, often times I find that I don't have a high enough resolution for my curve, and it starts to look chunky. As such, I need more cuts. However, I don't know how to add them. The Subdivide command works for this, in that you can select all faces and subdivide them as much as you want. However, that create a bunch of junk on the sides that I don't need.
I want to go from this:
to this:
without undoing, or deleting. Is there a way to do this via Loop Cut, Subdivide, or some modifier?
