Error VE268 and libraries

Recently I started to update a library from built 4.6 to 5.4. I also noticed this error on OCP. I don't understand why this is the solution on the wiki: "because the mesh file is referenced indirectly from the config.txt of some other asset (e.g. as a mesh library) without also being referenced in the config.txt file". The idea of a library is that other assets use these meshes, not your own asset.
If I have to have a line in the config of the library for each mesh, in some cases updating could be impossible. For example, in my high speed catenary I have more or less 200 meshes (including main mesh and lods).
Any workaround other than making 200 lines?
