Change summary period to last Friday of everyone month

[Revels]

Summary period from last < weekday > of month (eg: last Friday of the month)

Hi. Just started using the Budgets feature in Summary and it would really help to be able to set a budget date as “the last Friday of the month” rather than a fixed date! Any chance of adding this? Being able to see a summary based on when the money actually comes in would make budgeting much simpler!
