Grain size curves and boring name references

Hello

Our grain size plot can show up to 7 test results.  When outputing grain size curves, there does not seem to be a limitation that you can only print results from one boring on the the curves in the way we have it set up.  You can select whatever tests you want, from multiple borings.  I would like to know how I can list the borings that are shown on the curve in the title block:  "Grain Size Curves for Borings X and X".  I tried putting <<POINT.PointID>> in the title block, but it only prints the first boring, not the others that might be part of the same plot.   What code should I use so that it can list the names of multiple borings that might be shown on the same plot.

Alternatively, can I do something in Page Properties that only allows one boring per page or per plot?

Thank you for your assistance.
