Edit multiple objects with ReorderableList?

I've made a custom inspector that draws a reorderable list. Is there a way to get the list to work when I have multiple objects selected?

 

Please don't ask the same question twice.
Are you using the reorderable list in the UnityInterals namespace?
AFAIK they are just using Rotorz Reorderable List, which you could extend yourself.
However, there is a guy who already extended it. Probably his version of the Reorderable List is all you need.

 

I don't think I'm hurting anyone by asking one more time. I waited a week so I wouldn't be spamming. And asking again clearly had merit because someone who could help actually saw my question this time
Regardless, thanks for the help. The list extension you linked works perfectly.
