It would be helpful to have the ability to filter on single donations. The use case is we may want to pull donors who have ever donated more than $1000 in a single donation, to ask them for large donations again. With the "total amount donated" filter we can't distinguish between someone with a recurring $25 donation over many months and someone who donated $1K one time.

(It would also be helpful, but lower priority, to add a time feature on that same filter - "donated $1K in 2026" for example. That's not quite the same as just doing an AND on "donation date > 1/1/26" because maybe they gave $1K in 2025 and a small donation in 26. But that piece is less important)
