Trying to find this in the docs - I think I've seen it, but can't find it now. I'd like to include a non-python data file (like a csv reference table) in my pex build that deploys to dagster cloud. is this possible? I know I could put it somewhere else, and pull it in as an asset. But it really only exists to help transform one actual asset into another, so treating it as its own asset feels a little bit like overkill.
