That's a good question. You can maybe create a variable that's a
simple Python function to update it's value (the frequency) after a
timeout.

That reminds me that I wanted to implement a GRC function block so we
can define multi-line functions in a GRC graph, which would be much
more useful for something like this. Never made it from my head to an
implementation, though.
