Tithes and offerings.

I regularly tithe and give offerings at church.

I would like the app to have a feature that allows me to set up two expense categories (tithes and offerings) defined by individual percentages, rather than specifying a specific amount in currency. I’d like it so that within the tithes and offerings category, I could select which income entries should be included. For example: The tithe will be 10% of all income entries, so I select all income entries; however, the offering will be a different percentage applied only to some income entries and not all, so I select only the income entries to which I’d like the offering to apply.

Thank you!
