It would be nice to be able to select multiple categories. When I was putting together a report I tried to select all and add a 2023 category. This mis step overwrote all my categories for my transactions that year that I now need to redo. It would be nice if I could have an "income" or "inflow" category stack with something more general for batch retrieval. I know I can sort by date for this specific issue but I do think stackable categories would improve the user experience.
