Hello!
Not sure I understand so forgive me if I miss the point, but You could clip a new H/S adjustment to a group that contains your clipped layer. Grouping your layers and clipping the new HSL adjustment layer there will ensure the new clipped layer will only affect what's in the group.
Let me know if that was your question!
If not, maybe it's best to include a screenshot so we can have a better idea.

clipped HSL on a layer

same two layers grouped and a HSL adjustment clipped on the group
Note that the base layer isn't grouped so not affected by the second HSL adjustment
