Keybow MINI - Detection of key held down question

Hi all, Raspberry Pi and coding beginner here. I’ve had a search through the forums and have seen some old posts related to the Keybow 2040 that make me believe it’s not possible but:

When using the Keybow MINI is there any capability in the Keybow OS that recognises how long a key is held down for? The eventual goal being to switch between a few layouts so the MINI has more than just 3 shortcuts/macros. I’ve also seen there is an example in the library which turns one of the keys into a modifier key which would enable 4 key layout for the MINI.
