As a little more context, we are developing an opens-source multi-sig wallet using the polkadot tools that can be used by the community at large. We have a specific need for one, but want to donate our work to the cause.

Currently we have created the wallet and it is partly functional - we can send tao to it but we can't send from it. To send from the multi-sig wallet, or stake/unstake to a hotkey, we believe we need for multi-signature calls to be enabled on bittensor.
