https://forums.autodesk.com/t5/autocad-forum/how-to-change-a-multi-line-element-from-one-mlstyle-to-another/m-p/5810309#M313409 That's the problem with MultiLines. Once they are created, the style is not editable. You also cannot have curves around corners. I feel they could be used more if they operated similarly to Polylines.
