From Custom Column request to design selection

Hello all,

im on a report with SQL import datas.

For each row, i have different dates.

I made a custom column to find data that is more reent or older than a defined date, like this :

each if [InstalledOn00] < #date(2022, 10, 1) then "FALSE" else "TRUE"

how can do to allow to choose the date directly in the design to avoid to "transform data" each time ?

Thanks
