CustomTimeDilation needs setter + callback

It is just a property that gets set directly. I would like to know when it changes for an actor.

Building a custom anim notify system because Queued notifies often don’t trigger at all and branching point notifies often fail because more than 1 triggers on the same frame. For anyone making a production/release game the current system is inadequate. But I can’t make my timer-based system factor time dilation without a callback, unless I bind to mesh pose but a lot of dedi servers don’t want to tick the mesh pose.

TBH, its a very sloppy implementation that needs an upgrade regardless of use-case.
