Can you change an edge flange parameter, without losing your sketch

Best reader,

I'm designing a lamp from sheetmetal. It consist out a lot of small edge flanges. But i have to change some of the edge flange parameters to get it connected better. The only thing is when you change an edge parameters, you lose the sketch, and al the connecting relations. So i have to start all over again. Is there anyway to change, without losing everything. Please let me know

Kind regards,

It's like this. i created the plane, offset the entities from other small planes. But sometimes the edges need to be changed to create a better pattern. But when defining the new edge, it creates a whole new references which i have to set up all over again, as you can see in the second picture. So i would like to know, if i can change the edge, without losing the reference sketch that was created in the first picture on edge 1. Hope you understand the question better this time.
