Also you can create several pages in the Generic Remote panel to assign the same keys to different functions.
I have one page for opening inserted plugins, another for drum sequencing (quantize, logical presets to humanize hi hats, snares, etc,), another for recording vocals (pre-roll on/off, duplicate track with no events macro, etc).
Then have buttons 7 and 8 to navigate thru those pages up and down.
If you think about it, your F1 to F8 become (not sure if there is a limit) infinite function triggers (including macros, logical presets, etc)
