Changing brightness of one fixture for sequence in live mode

I have set up a “sequence of presets” and a button to start the sequence in live mode. I found that one fixture (defined as a group) in this “sequence of presets” is too bright. Is it possible to continue to use this “sequence of presets” and add a control to live mode to adjust brightness setting for that one fixture (group)?
Or do have to create new presets with the fixture at a lower brightness and add them to a new sequence?
Hope this question makes sense.


The presets are stacked by LTP, so the last is winner so if you put a slider and actionnate this after the sequence, it will have the priority
