When re-entering a similar transaction from history that involves a split, I'd like to be able to edit the Total first, and then adjust the split details as necessary such that the amount over or under the new total is calculated by MD as I update the splits. The behavior I see currently is that the total is read-only, and the only way to shift it is to edit the split details. But in a case where one split row just needs to have whatever amount is leftover after the other splits are taken off of the total, I have to back-calculate the last split row amount.
