not built in but if you're on linux you can always overlay ecryptfs on your password safe directory, or just have your passwords in a separate vm entirely that is used only for that
I don't have it running yet but I am planning to write something where you have a vm you can connect to with the same/similar command syntax and it would pop up a window of some sort saying 'I received a request for password xyz, yes/no' this way you can have your main system and/or other vms have access to the password store in a controlled manner.
If you have this vm running an FDE install then it would make it also super easy to backup all your passwords, just shutdown the vm and copy the vdi, would only be a few gigs (don't need too much software in this install, just the base system, gpg and whatever ncurses daemon to listen for password requests)
ecryptfs doesn't obfuscate filenames (it is a "stacked" filesystem) so that's not going to do any good. You'll need block-level encryption such as LUKS and a loopback mount if you want to keep that hidden, at least when that partition isn't mounted.
I just wish there was a built in way to encrypt the folder structure to hide what sites I have credentials for.
