No. I don't know what you really have in mind, but blocks are blocks and
not states.

You can always halt the flow graph and reconfigure it; for the problem
you've described I'd definitely use the tagged stream logic I tried to
explain.

You should have a look at reconfiguration. But much more, I think it's a
good idea to have a look at existing frameworks -- maybe you'd want to
understand the ofdm_rx example in gr-digital/examples?
