How can I use the same Key combination for several functions that are compatible?
In my personal case I wanted to 'Save the Windows Positions' and 'Launch the Screensaver', which not only are totally compatible functions but also make a lot of sense, because Windows tend to disconnect some displays when the screensaver is blank, and that moves all the app windows around.
This is currently on our feature request list, so I've added your vote to it. We'll be sure to let you know if/when we're able to implement it in the future.
