Dynamic expenses length

For inputting expenses, it would be nice if the tables to input this data weren't fixed in length but that we could add rows. E.g. for Miscellaneous expenses. This is important to me because currently I am using the miscellaneous expenses page to model my children going to two different K-12 private schools. I know (sort of) exactly how much it will cost at each school depending on the school's historical inflation rate, discounts, and other factors that are too specific to have a general cost+inflation. I need more rows to add other expenses I need to model (unless there is a better way).
