Zero port monitoring

I have an application that has services that operate on a large port range. So we've set up a zero port (wildcard port) virtual server.

On the pool side, I have a pool with 4 nodes and I'm forwarding the port from the VS to the same port on the nodes. I'm trying to avoid having to setup a pool for each service that runs on each port.

The problem is monitoring. I want to setup a monitor for each port in the pool, and if a monitor fails for a port, I don't want the entire node removed from it because other services (ports) may still be functional.

Essentially I want the LTM to be intelligent enough to do zero-port forwarding but realize that if a port monitor on one of the pool members is down, stop forwarding requests for just that port on that node (use a different node), but continue servicing the other ports.

Is this possible or do I have to have individual pools for each port so I can individually monitor them so they can go down when one service/port is unavailable?
