Hi Matt:
The answer is, not currently. However, we are reworking some of the setpoints/limits/parameter classes in Brick for an upcoming release. Having a "point of a point" is something we have discussed before -- I do think this makes sense to do, and we will revisit it for an upcoming Brick release. For now, I think just make the points "flat" (i.e., not a point of a point) is the best we can do.
Best,
Gabe
