AI Tree Play Animation (Randomly Selected from Variety)?

I have varieties of animations and want to randomly choose one of the variety.
How can I do this and have it play on my character?
Then when it is done finishing its play, go back to the character’s animation bp?

It is possible by use of the animation montage (or multiple montages). You can select section by specific logic in BT task. Also you can read parameters of the section such as duration, time etc. I am not sure that all features are available from blueprints.
