Determine if a "Set View Target with Blend" is in in the process of blending

Hi Community,

I have a scene with a lot of possible player-triggered camera transitions using “Set View Target with Blend” and to prevent jerkiness I was hoping for a way to determine if a “Set View Target with Blend” is running.
However, I have yet to find such a solution.

Is there any built-in mechanic to find if a blend is in progress?
