That sounds dumb unless you are somehow unable to set savings budgets yourself. And if you can't manage a savings goal like 'set up automatic transfer for $200 to my savings account every month', you're going to have a real hard time with FIRE.
When I was starting out, I played 'savings chicken' whereby I set up automatic transfers, and when I didn't notice $50 dollars missing every month, I upped it to $100, then $200, then $400, etc etc, you get the picture. And I didn't have to give some sketchy company that didn't pay interest access to my accounts!
If you want to max your IRA (I'm assuming this is what you mean when you say 'Roth'), figure out how much money you need, divide it by the number of months left in the year, and then set up automatic transfers for that amount to your IRA account.
