Oopsy Param modifiers?

Ahoy all! Quick question on what I might be able to do with switch params inside Gen~… Specifically something like an argument that would return a float representing the number of seconds the switch has been held down?

There’s something like this in the PD integration, but I haven’t been able to find anything like it for Oopsy? In another post, Mr. GrrrWaaa explained things like:

E.g. [param cv1_int_foo @min 0 @max 4] will only ever send 0, 1, 2, 3 or 4.

Also, [param cv2_bool_foo @min 2 @max 5] will only ever be 2 or 5, etc.

Is there more here than just offs and ons?
