Link savings accounts and smart goals

I use one of my bank accounts as a savings account, and I wanted to create smart goals to divide this money in this one account (eg half of it goes towards a new car, the other half towards dream vacation) but if I make a deposit in a smart goal, it takes the money away from the account, when in reality the money hasn’t moved from that account. It would be great if we could put money in the smart goals without it going away from one of the accounts. It would also be great to be able to take money away from the smart goals if some of it was spent before the end of the goal.
