Custom Shortcuts on KM717?

I really like the KM717 keyboard but I do wish it had more FN shortcuts.  Since about half the function keys don't have a shortcut assigned to them when you press them in combination with the FN key, is it possible somehow to assign custom shortcuts to these available function keys?  If so, how?  Also just to clarify, I'm referring to pressing the FN key and one of the F1 to F12 keys.  Creating normal shortcuts in Windows is simple.

Thanks.
