hi ! i'm new at using Notion formulas. i wonder if i can use it to automatically fill a column which is not a formula. i'm trying to create a ring that shows my progression.

i have :

column 1 : Status

column 2 : #Number (showing as ring, not as number)

column 3 : Formula

what i want to do :

if Status = completed, i want #Number to be 2 (which is a completed ring).

if Status = in progress, i want #Number to be 1 (which is half a ring).

if Status = not started, i want #Number to be 0 (empty ring).

but i don't know how to write a formula that changes another column, not the formula one.
