Quick selections of materials in the Static Mesh or Blueprint Editor is not possible

Hi,
since the last years I have always problems with one thing: I cannot select directly materials of my model, for example in the static mesh editor. I have to work with a combined mesh of a car with 200 material slots. It´s really a pain to find always the corresponding material in the mesh. Why is it not possible to click on a definite part of the 3D mesh and you get immediately a selection of the material which is used for this part? In other programs this feature is integrated.

Exist a shortcut, a workaround or something else to solve this problem?

Best regards, Andreas
