I call it housekeeping.
It's even tougher for me. I have O scale 2 rail, 3 rail, and G scale all running with MTH DCS.
The grandkids were learning how to add and run engines. Things got messed up pretty bad.
I finally realized that it was easier to put the G scale into their own remotes. Before that, it was a bigger mess.
I did make a chart of engines and their address. I let it get old and not up to date with changes. So it became useless.
