Populate a figure on the same date each month

Hi All, If I have a whole year worth of dates in a row eg 01/01/2022 02/01/2022 03/01/2022 (Aus date format) is there a way to populate the same figure (in this situation lets say $800) on the same date each month. For example is a row below the date row on the 2nd of each month populate $800.

So; 02/01/2022 $800

02/02/2022 $800

02/03/2022 $800

02/04/2022 $800

02/05/2022 $800 ext ext.... Thank you.
