you cannot dynamically change the number of outputs

Perhaps you can add a checkbox "Single output with topics" (or something like that). When activated, your node gets a single output (see here). And all the output messages will be send to that output, but you specify a topic on each output messge. That way the messages can be routed/filtered afterwards in the next nodes of the flow.
