Thanks for the reply, Paul. The yellow control handle doesn’t seem to work consistently for me. I was able to move 4 of the 5 Milestones to where I wanted them, but one stubbornly refuses to align. It positions quite easily and precisely if I drag the yellow control handle along the length of the Milestone, which will give me either the perfect horizontal *or* vertical position but not both.
If I pull the yellow control handle down vertically, it pops right back up to where it was. If I pull the yellow control handle horizontally, it will stay in the correct horizontal position but at a vertical position parallel to the existing Milestone line. Pictures below; I’m stumped.
