Various light working with one timeline

hi folks,
i am working with many individual torch-lights per scene, and all of them should move slightly in place and change intensity while playing.
so i created a timeline with two graphs. one for intensity and one for position
it works very well for a single light.
connecting all lights to the same timeline works, too but looks really stupid and unrealistic.

now my whish.
instead of creating a new timeline for every light to make it more realistic… (whats very timeconsuming and a pain to do)
is there a way to connect all lights to these two timeline but add a unique starting point and unique play speed for each light ?
so every light behaves different than the others.
if please describe it in an easy way, cause i am an absolute beginner in blueprints.

another thing is while having all keypoints in the timeline selected, is ther a way to stretch / shrink them horizontaly on the timeline or verticale on the value-line.
would make changing timelines much easier

thx
ingo

afaik there is no way to change the time or value of a timeline outside of the node. Possibly in the future as this made me have to change how one of my mechanics works as well.
