Fidelity's cash management accounts let you set rules. I have one CMA for general funds where my paycheck is deposited and a second CMA that is configured to keep itself at the value of my next few months of fixed expenses. It will grab money from the general to top itself off after something is paid, and the general in turn automatically sends excess to an investment account if its value gets too high. Basically the only thing I do is check the autobill payees to make sure none of them are doing anything stupid. I have some trouble with executive function but I have not missed a bill in years because of this system. That might not seem impressive but losing money to late fees is a recurring theme in adhd communities.
