I mean not to exclude from already existin multi sig wallets, but create a wallet with such possibility.
For example: The team of 4 people want to accept temporary 5th member (give him the right to control the wallet on equal basis as others) for 2 month. But the initial group (of 4) should have a right to exclude him. Or even automaticaly after this time period this member should be excluded from the wallet owners group.
Any ideas or suggestions?
