Accessing Static Meshes Added/Set in Blueprints

Thanks for taking a look at this; I really hope you can point me in the right direction…

I’m messing around with Add Static Mesh and Set Static Mesh in blueprints, and using it to set up a row of static meshes in a fence or wall-like repeating pattern (one after the other). It occurred to me that it would be really useful to be able to click at a point in the line and alter that mesh (“Click to place gate here” kind of thing).

I can select the static mesh by double-clicking or right-clicking, but the context menu (right-click) offers limited functionality. Is there anything I can use to extend my options and replace the selected static mesh, similar to the way I could replace the actor in the normal context menu?

Thank you!
