I donít think there is any short cut to what you are trying to achieve, especially from set to set.
I use mostly cable sliders, especially for beaver. I have a swivel at the end of the cable. I use several wraps of 14 gauge wire to fasten it to the anchor. I rarely try to transfer these rigs intact from set to set. Usually I just cut the wire, and start over again at the next set.
Iíve racked my brain for a faster way myself, but I just canít come up with anything that is as secure as some tightly wrapped turns of wire.
