AutoCAD Inventor :: Unique File Naming From Library Or Content Center?

I'm having some problems giving certain parts in my assembly a unique file name. Im reorganizing all of my projects in a

- content center
- designs
- libraries

way, where my projects are under designs and commonly used parts under libraries.

Now i have something like a pump. I can derrive this assembly into a solid and put it in the content center, or keep the assembly and put it in the libaries folder. since this is a part i use in multiple projects.

Now my problem is that this pump has a different name in every project, and a library part doesn't allow me to change this name. Say standard name is "centrifugal pump" while the name in project 1 would be P101, while in project 2 it has to be named P501 and so on in order to match with the flowcharts.

Is my only option here creating a solid out of these components and putting it all in my content center ( leaving my libraries folder totally empty ), adding it as a custom part afterwards ( so i can rename it ). I rather have it in my library folder, since this will keep my design folder organized without hundreds of duplicates of this pump, using different names. Besides i rather have it as an assembly so i can assign the connecting tubes of the pump to different sub assemblies of piping.

Different example, a butterfly valve excists out of 3 parts. the valve itself, and 2 connecting tubes. possible to dissemble. all 3 parts need to have the same file naming say XV900. 1 side of the valve needs to be assigned to pipe-01 while the other side of the valve needs to be assigned to pipe-02. Content center doesn't allow me to split files, but allows me to use unique file names. A library party allows me to split files ( if not read only ) but doesn't allow me to change names.
