Automatic boolean toggle when data is updated

I’m having a hard time finding away around this issue.
I need a boolean function where the output is a constant False, but switches to True any time an input data updates.
This is very useful for running Galapagos for example, and being able to react to each iteration.

0 being false and any integer being true, list length +1 on a stream filter should do it.

edit: Never mind, that only works on components taking buttons. If statement is the way to go.

Any practical solution yet (No code) This seems like a very useful thing to have.
