Levels levels levels

I have a converted dwg  to dgn file utilizing model and sheet. I can't believe the amount of locations that it's possible to change a reference level's display properties, not to mention the fact the process is multiplied by 2 for on/off state changes. I'm completely overwhelmed.

I realize the initial creator of the file is mostly to blame but could someone help me get a handle on this? I'd like to control all the levels in one location. Additionally, I can't seem to find a setting to hold the level settings so they all revert after open/close. (dwg visretain=1 already??)
