Handle recurring (but not monthly) expenses in budget
Example: I have a monthly « Presse » budget, for a subscription that is paid every month but I have also subscriptions that I pay once a year. I can put my monthly subscription in a budget but each year, I have months where the budget is not respected since this is the months where I pay my yearly subscriptions.
Solution: I should be able to say "my Presse budget is 5€/month but it increases by XX€ on september and XX€ in march".
