I know that I can wrap it with 'plumbers tape' and nail the tape

fitting. How about mid-length? It would be easy if they made a
'glue-on' (ABS) quarter circle with floppy straps that could be
nailed to the studs.

If you are currently building this, then the easiest thing to do would
be to add a standard coupling where you need to support it. Then you
can wrap your plumber's tape tightly around the pipe just below the
coupling.

If this is an existing stack, you can still achieve the same effect:
Take a standard ABS coupling and cut it half lengthwise. Remove the
stop from each piece any way that you like (including just cutting
each piece shorter right next to the stop). Now you can cement the
two pieces onto the vent stack wherever you need to support it.
