Be able to choose envelope by seconds (time)

Pease be able to choose between envelope by time (seconds) or percentage of sample size (as it is now).

I have been trying to use the loop function on waveforms like many use on the Elektron Digitak to make leads/bass… but on the S2400 all envelopes are based on sample size. so when looping a waveform is very small (less than a second) the envelope can never be bigger than that making it very impossible to make bass leads…

Thank you
