Tiling options for non-UV projections (cylinder, sphere)

In comparable applications, it is often possible to define U and V wraps (width, height) for non-UV projections. This allows for cheap and easy texturing workflows. Currently, these options don't seem to be available in blender - trying to modify the projection for tube mapping, for example, you can change the tile interval along the tube length, but there's no apparent way to change the repeats around the tube itself.

It's a similar story for spherical mapping.
