Change Transform of Cinematic Camera in Blueprint/C++ in Play Mode

Is it at all possible to change the transform of a cinematic camera assigned to a sequencer. In play mode I would like to change its transform before rendering it, but that doesn’t seem to work via Blueprints.
Even stranger (see pic below), I can see that my cinecam in the Outliner correctly assigns the new transformation (100, 100, 100) while in the sequencer the same camera does not. So it seems to me like its value is passed to the sequencer once only before I press Play.

Is there a way to fix this at all?

maybe try keying it?

thanks, I don’t know how to do that using blueprints. My goal is to render a single frame from a cinematic camera and all I want to do is be able to change the transformation in play mode. This doesn’t seem to work, at least not using SetActorTransform etc.

you key the transforms you have circled in green?
