Set a Minimum / Maximum Length of Song

Sorry if this was posted before - but I would like to set max / min or average duration per song - for my mixes, I prefer a 1.5-3 minute length for songs. Averaging about 2 mins per song.

A hard limit is likely unrealistic - but being able to say play at least 90 seconds of each song but no more than 180 seconds of each song would be game changing. (including or excluding transitions)
