Hi inesse

When adding in new item from the Modular Configurator (like a collar for example) it will always come into the new project as whatever material/fabric it was originally assigned to. Once you bring in into the new project all you need to do is then reassign to the proper fabric. From there all the colorways should update accordingly as long as each pattern was assigned to the correct material.

If this does not answer your question could you please explain further or add a few visual images? Thanks!
