BT Task executed in time

I’m wondering how to make a BT Task that is executed during more than one frame, like Rotate To Face BBEntry.
I need a similar task, but I want to make my NPC to rotate to copy another rotation stored in the blackboard.
How can I do?

Ok, I solved this by myself: instead of Event Receive Execute as an entry point for the task, Event Receive Tick must be used.
Of course, somewhere a Finish Execute node must be reached to terminate the task.

I highly recommend doing any task that requires updating in C++. They are 10x faster than blueprint tasks.
