How to select controls on two different control rigs in UE5

I currently have two metahumans in my level sequence but you can only select the controls of one of them at a time (unlike in Maya).

Is there a way to select controls on two different control rigs at the same time and key them? I’m trying to have one character move the other character’s hand and currently, I have to just eyeball the translation etc. of the first character’s hand in relation to the other character which isn’t really ideal and is very inaccurate.
