Anchor in skeletal animation?

I’ve used some engines that have anchor feature in their skeletal animation system.
It’s used when you want the actor to be perfectly aligned to play an animation.
For example, when you play an animation to climb a ledge, you don’t have to perfectly place the character at a certain offset to ledge. Instead, you set an anchor point you have agreed with your animator and set in how many frames you want the animation displacement gradually aligned.
I don’t find any related feature in UE4 document.
Does anybody have suggestions?
I know I could manually achieve it. But having this feature is more convenient and data driven.
