I believe you're the first person to ever ask about this. Limiting the controllers to 99 meant that we only needed two digits to display them in menus. Also the majority of guitar players using MIDI CC only use a couple of them, so 99 seemed like plenty.
You might be able to translate the MIDI CC numbers up with a laptop but not with the Factor Pedal alone.
In the MIDI / RCV CTL menu you can assign TAP to any MIDI CC in the list.
