Applying diffuse alpha map on multiple materials at once

[Cloud07]

Hello everyone! I'm new to Keyshot, using it to play with some models that I convert to OBJ files from the XPS software and when I imported  model, it comes with many layers for the hair and I was wondering if there is a way to apply the diffuse alpha map on every hair part rather than going one by one.

Group select them in the Scene Tab. With them all selected drag and drop the material on one of them.
Another way is to create a Search for them if they all have the same name or partial name. Enter the name, or part of the name that is common and unique to all, in the search bar. When they are selected then RMB click on one of them and from the pop up menu select Material>Link Materials.
With them all selected you can also put  them in a Group for better management.
