Chris, please bear in mind that I have not tried this, but I believe that the sequence you need is, basically:

G91 (set relative mode)
G0 A95 (turn axis but deliberately overshoot)
G0 A-10 (turn back to lock position)
G90 (switch back to absolute)
G92 Axx (where xx is the value you want to appear in the DRO display at this point)

Alternatively, if you are resetting the DRO to the correct position each time, you can probably skip the switching relative/absolute bit. Turn to the required angle plus a bit of overshoot, turn back by enough to make sure that the axis is back on its ratchet stop, then use G92 Axx to reset the DRO to the correct value. Absolute moves should then work OK. Good luck if you want to build this into your post-processor!

Yes thanks for that it's been a long time since I used a G92 but I understand it,
