For Dimensions, there are two placement options for GTOL's: "dimension elbow" as well as "on dim" (below dimension).
For notes, there is no such “on dim” (below dimension) placement. Currently, only “elbow” placement exists. "elbow" switches the leader type to underneath the note and runs it the width of the note to attach the GTOL to the end. Currently the only way to add a GTOL to the bottom of a note. To force this, the GTOL needs to be placed separately and referenced inside of the note using &g## (for model based GTOL's) and &dg## (for drawing based GTOL's).
Please add a "on note" placement option that acts like the "on dim" placement option.
