You might try a 1-foot or so length of cord (I use 550 paracord) with loops at each end. One loop goes to the suspension connection point, runs down the ridgeline, the other end clips to the UQ shock-cord. You can vary the length to get the best fit.
If you have several hammocks of varying lengths, you can use different length cords to compensate, the same UQ suspension is used for all.
