SEQV3: how to Fade a track in or out

Hey communty,

 

I need a tip, how i can adjust a track to fade in or out in an easy way. Is it possible, so that the track starts at 0..127 (e.g. 100%) and as long as it repeats, it should not fade again?

(Fade out idea could also be needful.)

 

thanks for any adwise.
