There's the pass-code extension for that:

https://github.com/alpernebbi/pass-code

> A pass extension that obscures the filenames and folder hierarchy within your password store.

> pass-code generates random filenames for each file in the password store and keeps the mapping in an encrypted file. This way, no valuable information is accessible even if your password store is leaked to the public (unless your GPG private keys were also leaked). Nevertheless, you should always ensure proper protection of your password store.
