You don't have to create a new context, but you'll need to:
delete all rules
repopulate context with rules you'd like to keep build context.

Or as you said - just create new context, populate it, build, destroy old o=
ne.

Yes, in theory up to 64 fields allowed, though on practice I never used mor=
e than 11 so far.
