Suggestion: save sets of Port selections, and allow to select between the sets.

Currently there is only one set of ports stored in the Port Selection. If I run a scan using a list of ports, and then I want to run another scan with different ports, I have to delete the existing selection and re-create it. If there are dozens of ports in the list, it can be difficult to save them all and restore them later.

So if multiple sets of port selections could be saved and maybe named, and then selected from at scan time, it would make this tool a lot more flexible.
