I have a set of polygons which has been clipped at one point in time. I would like to dissolve them back together but only along the path originally used to clip them. I don't want to dissolve all polygons touching each other.
My approach so far has been to locate the edges of the polygons I would like to remove and I have marked those in the image below (I have the markings as features). I don't have a common ID on the polygons I would like to dissolve, so I haven't found a way to group the polygons to dissolve them in that way, since one polygon might have more than one marker attached.
How can I achieve what I have outlined below?
