this may be not new or even a good idea, but it is simple. i tested this for seven-eight nights & it works (for me ). hope this will help someone and would like to hear your thoughts!
below is a photo of the head end of the suspended uq (mw3c) only showing the left side shock cord to be longer (than the right side one) giving more coverage on the left (left shoulders if lying on the back).
at the foot end the left side shock cord is short and the right side one is long, giving more coverage on the right (footbox).
after this, tighten or relax everything as usual and/or as needed...
