FEATURE REQUEST -- ability to turn on/off ports

First post. Hope I'm doing everything correctly...

I have a few processes I like to occasionally access remotely. So, I like to only keep those ports open while I'm accessing.
Under:
Administration / Virtual Server/Port Forwarding, in the Port Forwarding List:

I wish there was an option to check/uncheck the ports I'm currently forwarding. As it is now, the only was to "uncheck" is to delete the entry.
