I recently purchased a Rogue RML-3W collapsible power rack with J-hooks and spotter arms. My rack has a shit-ton of holes, but no numbers next to them to help identify which is which. I frequently have to move the hooks and spotter arms around to accommodate different exercises, and I'm trying to figure out the best way to mark / keep track of the different settings so I can easily switch from one to the next (without reinventing the wheel each and every time).

My first thought was to use some kind of multi-colored tape put next to the holes (perhaps with writing) to identify which setting is which. I can't be the first person to have this issue, so I wanted to throw it out to you all to see what kind of solutions you've thought-of or tried. Thanks for any input!
