Unable to add additional polkadot validators

[pietje429]

In other wallets (like ledger) you can create a list of up to 14 validators in which your coins shuffle to have active validators as much as possible. in Airgap ault i'm only able to select one and the only option is to 'change validator'. I can't add a validator, which is usual in polkadot. because of this my stake is inactive a lot.
