Why can't I use remote grades on timeline clips

hello everyone
I have a main timeline that contains other timelines inside it. Basically, I have the same timeline repeated several times inside a bigger timeline. I want to apply the same grade to all of those timeline instances.
In the Color page, when I try to create a remote grade, it doesn’t work. The option isn’t available like it normally is for regular clips that come from the same source. Usually with regular clips, I can create a remote grade and have it affect all the clips that come from the same source file. But with these timelines inside timelines, remote grades aren’t working. Why is this ? And what if i still Want to do it ?
