Is it possible to set up 2-of-3 multisig, e.g. with three trezors, while using a passphrase on one, two or all Trezors? Such that every time you unlock the wallet to interact with Electrum, you enter the passphrase? This way the seeds can be stored in separate locations, but even access to all seeds would not allow access to the multisig bitcoins.
