Allow more then one hotkey shortcut per action

Suggesting to add a way to be able to assign more then one hotkey shortcut per action.

Some examples:

Maximize Window
The default for this is Super+X
What if user also wanted to use something like Super+Up as well
Which mimics how some set dragging window to top of screen activates window being maximized.

Tile Window To The
The defaults for these are Super+Left, Super+Right, etc.
What if user also wanted to set these up in number keypad as well.

Sometimes it is nice to be able to have multiple shortcuts to achieve the same action.

Thank You
