I would suggest loading the material pose files onto a prop. Poser will ask whether to create materials if they do not exist. You can then edit the materials on the prop, though it won't be visible except as a preview in the Material Room, as the prop won't have any facet groups associated with the dress materials.

If you pick a prop like the box, which only has a Preview material (everything always has a preview material, as Poser will create it even if the obj file doesn't refer to it), there won't be any extraneous material names, so you can save the modified shader trees on the prop back to the library.

Poser is by far the best tool for editing material pose files. It can be done directly with a text editor (provided it can automatically handle compressed files, like Notepad++ on Windows or BBEdit on macOS), but you won't have any of the GUI features like dragging nodes around to adjust their position coordinates, and if you make a typo, you can break the file completely.
