I may be misunderstanding the question, but yes.  The propeller code
for constant speed props simulates a governor which automatically
seeks to a the selected RPM.  This is used by the solver also, so you
can just specify the position of the pitch lever and expect to see the
same results at runtime.

There is also a manual-pitch attribute you can set, but this
feature is really touchy and hard to get right.  You need to
get the pitch dead-on at solution time (the job the governor does for
you normally) in order for the resulting propeller to match the engine
properties at runtime.
