How to Select most of materials in the Material Clean up Dialogue

[orchidworld]

Hi,

if there are 500 orthotropic materials,  i want to Clean 200 orthotropic materials, i have to select materials one by one, it is forbidden to drag or use "Shift/Ctrl" to select many materials one time. i think it is inefficient.
If can it  add this function next version?

That's a good idea. We used to have a "material filter" option. You could apply a filter based on material type, stiffness, density, etc. and only those materials would be displayed on the material cleanup form. We found that the material filters were not being used so we decided to stop supporting it.
