Thanks for answering Mark.

I was thinking of doing lots in one go, as one of my files is a bit of a mess. It has lots and lots of shaders with different names, but they are all the same colour.

I'd also like to be able to search for a named item and be able to assign a texture to the found ones, without having to group them together.

As an example imagine I have a room with 10 bunk beds and I want to change the colours on the legs to one colour. At the moment the only way I can do this is by grouping all of the legs together, which would take them out of their bunk bed groups.

Perhaps a plugin like this would be useful?
