Multiple keyring support?

I manage multiple encfs stashes with strong passwords, and entering them is indeed a pain, particularly the ones that I mount on most logins. However, I also want to use a password to unlock these stashes that is much stronger than my standard linux login/sudo password.

The answer already seems to be baked in: GEncfsM supports Gnome keyring, and the Gnome keyring manager supports multiple keyrings. So what I'd like to do is just have the passwords stored on a different keyring to the usual Wifi and network passwords and such.

My question is: is this actually possible as it stands? The option to add stash passwords to keyrings is just one check box, and checking it automatically adds the stash keys to the default "Login" keyring. I don't see anything in the command line or GUI preferences menus that would allow me to specify the keyring.

I think that what should happen when a user clicks "save password in keyring" is for a menu to open prompting which keyring to save in. Then, when the user attempts to mount that stash, GEncfsM should simply check whether the designated keyring is locked or unlocked and prompt for an unlock password if needed.

Is this a capability that exists but that I'm just missing, a capability that would be trivial to add, or something that is actually not very feasible?

Thanks very much for your help.
