Selection tags for primitives

For Extruded objects C4D offers the selection tags: R1, R2,C1,C2. (Rounding and Caps)

It would be very usefull to have selection tags for other primitives.

e.g:

A sliced tube should have tags for the round parts, the caps, the roundings (if applicable) and the slice planes. (B,C1,C2,R1,R2,S1,S2)

If this is implemented, we should be able to make the colour scheme below, without making the primitve editable.
