Query w/ Multiple Dates

Hi there,

Does anyone know if there is a way to add multiple of the same field to a query? For instance, I have a query of all of my organizations investors and a UDF saying what their first installment date is (what quarter they became an investor). I want to me able to capture all of them by quarter for separate years so investors with July installments from 2020 and 2021 in the same query but can't seem to find a way to make it work.
