Making battery saving mode more customisable

Under brave://flags, there is an option to enable the performance tab in settings. If this is implemented, can there be more toggles to customised the limits? Right now, if you turn power saving mode on it rids of smooth scrolling and smooth video frames, as well as background activity. Can you customise it so that it only removes smooth scrolling and background activity? I would like to keep better video quality individually with the other options in tact.
