Availability Of Parallel Cord For Connection Multiple Go Power! MPPT Solar Charge Controllers GP72RR

Question

Question:

The manual for the eTrailer part GP72RR Mfg part: GP-RVC-MPPT-30 says you can stack up to 5 of them in a parallel configuration using a parallel cable. Im planning out some additions to the solar system on an RV which already has one of these controllers. Instead of replacing a perfectly good controller with Victron, which is easily joined together in this fashion, I wanted to to purchase a second controller for the RV, join them together as indicated in the documentation, and manage them with the same remote. That said, it seems to be made of Unobtainium. I cant seem to find the indicated parallel cable separately anywhere, nor does it doesnt look like eTrailer part GP72RR includes it either. Help?
