Yes. It runs the union of the state-file and what you give it on the command line. E.g.:

  $ rm .prove
  $ prove --state=slow,save t0000-basic.sh
  No saved state, selection will be empty
  t0000-basic.sh .. ok    
  All tests successful.
  Files=1, Tests=77,  1 wallclock secs ( 0.03 usr  0.00 sys +  0.08 cusr 0.06 csys =  0.17 CPU)
  Result: PASS

  $ prove --state=slow,save t0001-init.sh
  t0000-basic.sh .. ok    
  t0001-init.sh ... ok    
  All tests successful.
  Files=2, Tests=113,  1 wallclock secs ( 0.03 usr  0.00 sys +  0.06 cusr  0.10 csys =  0.19 CPU)
  Result: PASS
