Change actor sublevel at runtime

Hello,

We use level streaming and we want to allow characters to switch from a sublevel A to a sublevel B. Actually, unloading a sublevel destroy their characters.

Is there something I can use to change an actor sublevel at runtime or must I cheat and place them on persistent and enable / disable them when needed (that would be a lot of work as I need to hide them, disable all components, disable AI, …) ?

Thanks a lot.
