Yes.  But not anytime soon.  While it appears like a rather small thing,
it is fairly fundamental to how the GRASS environment behaves.

No real easier way than:

GRASS > grass5 /path/to/database/location/mapset

Note: you can leave monitors active when you leave GRASS, open another
monitor (say x1) in a new session, draw to it, exit the session,
go back to the other location/mapset, d.mon select=x0, and you can
continue to use the monitor.  A little more complicated with the 
TclTk interface (but not too much).

Note: Iff you're remaining in the same location, but want to reference
data in other mapsets within the location, you can.  See g.mapsets and
use data at mapset to reference them (read only...).
