How do I repositioni a piece of jewelry on my character using outfit studio?

[Fixadent]

If I wanted to resize/reposition a piece of jewelry in Skyrim Special Edition (like move a ring to a different finger) using outfit studio, and save my changes, how do I do that? The last time I tried, it caused CTD immediately after loading my saved game because I edited a mod item in outfit studio. Do I need to check "copy to bone weights" and do I export with or without reference?

Everything loaded up just fine after I uninstalled the mod. Thank goodness I didn't do it to a vanilla item or else I could have corrupted the entire game.

I'm using the CBBE female body, if that's at all relevant to this question.
