As a user who spends primarily on a credit card, I would like DAS to view all of my accounts (checking and savings) as a big pile of cash so that I can move money freely into vaults.
Context: I bank with SoFi and want to keep as much money in their savings account to get that sweet sweet APY. Since I spend primarily on my CC and use the CC integration, I am able to use my SoFi savings account as a "checking" account in DAS. Because this account is marked as checking in DAS, I am unable to use the Vaults feature.
