Render Content Name Conflict - Dialog Box


I am working on a large project that requires having multiple parts of the project in separate rhino files. The separate files are then actively linked into a single ‘master’ rhino model.

I have identical materials in each of the models that I don’t want to be ‘renamed’ upon linking them into the ‘master’ rhino model.

In the attached image, I would like the materials of the same name to remain as the same name rather than one of them being renamed.

There used to be a Dialog box that appeared when importing a material of the same name as an existing material, but this no longer appears. Is there a setting somewhere, or a registry that I can edit to have this option?

Thank you for your time,
