Turns out this is pretty easy to do.
Edit the script "Click in / Drag Event" and insert the new lines in the screen shot below. Add this section right above the "Continue without drag..." comment already there, between it and the End If directly above it.
Note that if you click on overlapping events (more than one) we don't offer the option to delete, both events are brought up.
