Changing the frame rate of animation sequences in an animation montage

I have two animation sequences that must be played one after the other in a loop. Both can have their frame rate changed during playing with a Blueprint. What animation tool can I use to do that?
Can I change the frame rate of the animation sequence individually in an animation montage?

I’m not sure if you can change the frame rate of an animation at runtime, if there is a way I have yet to discover it, I do believe you can adjust it in montage though. I know forsure you can adjust it in the animations settings itself, could always duplicate the animations and set each to the desired playback speed, probably not the most efficient way but should do the job

Thank you for your answer! But I believe more and more I should rather maybe use control rigs, as the durations of my animations on skeletal meshes depend on some control parameters…
