I’ve seen this feature request mentioned by someone else on the Trello board, but it was in a comment on a card in the Live section “Budgets: Spending Plan & Budgeting” and unless I’m missing something, it’s not yet a feature so I wanted to highlight.
I would like different Spending Plans to toggle between, I also have joint and personal accounts and I manage the spending separately. At the mo, I have the MD Spending Plan set up for just the joint account and budget my personal accounts offline with a spreadsheet - it would be a real timesaver would be if I could ditch that too.
N.B. if you did offer multiple Spending Plans I would probably have one joint, one personal and one that combined everything.
