Manage Attachment Entities - which module to choose for Product Information Master

Summary

There are multiple selections when building a new attachment entity, but no option for PIM

Hello, 

I am attempting to create a new attachment category in PIM. As of now we only have a 'miscellaneous' category available (see screenshot). 

In order to create a new attachment category I believe I need to create a new attachment entity, and then add a new category.  When I am building the new entity I do not see PIM as an option in the Module Name. 

My question is: which module do I want to use in order to see the new attachment category in PIM? Is it 'Product', 'Product Development' or 'Product Model Common'? Or another module?
