I can kinda do this with my bank (a small credit union) with a feature called Recipes. Basically a Recipe is a IFTTT-like interface where I can say "if my balance in CHQ drops below $1k, transfer $3k from LOC to CHQ". Likewise when the balance goes over a certain threshold, I can pay off the LOC, or if that's all paid, transfer to mutual funds or what have you.
