Load level from PAK file at arbitrary path

I’m able to load stuff from PAK files just dandy, including levels, but one problem I’m having is that when I load levels, if there is any deviancy in the path I mount the PAK at, it loads an empty level. I opened a umap file in a text editor and it seems like everything in there just has a hardcoded path (Game/SomeFolder/SomeAsset etc) and if it’s not exactly like that when I mount it and access it, it doesn’t work.

What I want to be able to do is mount a PAK containing a level at some arbitrary location (Content/MyMaps/) without demanding that exact folder structure when the maps are created in some other project. Is that possible?
