Make a binding actor move smooth at Begining in Sequencer?

Hi, I want to make a level sequencer has two steps
1.A actor move to the front of a stone,
2.Then climb on it.

The problem is that the actor who trigger this sequencer is not in a determined location, but a sector area that can reach the stone.
Now, I think if I can make the actor move to stone from his real location instead of the location made in the sequencer, that will be better.

I know I can do the step 1 using some C++ or BP code, but this is not my first choice. I wonder if I can achive this by sequencer only.

The releative transform section seems can do this, But I didn’t figure it out.

So, anyone knows how to achieve this?

Thanks for any Suggestion.
