How to add(edit) animation(node) in Animation blueprint during runtime?

In my AnimBP i have “Random Sequence Player”.
I can populate it with animations during editing, and everything is ok.

The question is:
How to add/remove/replace animations in this node dynamically?

i.e. i have 100 animation files in my project. But i want use only 3 in “Random Sequence Player” . I want to define set during runtime.

In common, how to pass parameters in “Random Sequence Player” ?
