Thanks for the above replies. Unfortunately, I don't quite see the solution.
@vojo: I can add a small stub with an arrow the shape I'm trying to connect to, but the issue that I think I have is that if I then try to connect a dynamic connector shape to it, there won't be any arrows midway in the middle of the dynamic connector where there are bends (i.e. right angle turns) in the shape.
As a workaround, I attempted to add a small arrow exactly at the bend in the shape, and I was planning to group both the arrow and dynamic connector. The unfortunate issue is that my dynamic connector keeps automatically rerouting on me. I followed some advice (from a Google search), to have the dynamic connector NOT reroute when I lay the shape on top of it. That works, but when I move one of the shapes, the dynamic connector moves, but NOT the little arrow, despite me grouping the arrow and the dynamic connector in the first place. So, that's some frustrating behavior.
@wapperdude - Thanks for the link. I do see that the user added an arrow onto a straight line. I do like how you can "move the arrow" to wherever you want along the line. But, what I'm is use that same idea on a dynamic connector that is allowed to have a left or right turn. Do you know if there is a way to extend that idea to a dynamic connector which will automatically reroute when one moves the shape it is connected to?
@Yacine - Thanks, It's not really at the beginning or end of a connector where I want to add a shape. It's at the point, somewhere in the "middle" where a dynamic connector takes a right or left turn. I could always add 2 straight lines, and "manually" have them connect to each other at right angles and then group the shape. But, that's getting more onerous than I want it to be since I have a complex schema, in which I might have to move various shapes to keep them looking good.
So, not sure if there are other solutions out there, or if I'm missing something from one of the suggestions already provided.
Thanks,
