Applying conditional formatting formula to 1000 rows without changing row number

This might sound strange but I am trying to apply the custom formula in the conditional formatting rule to 1000 rows:

=AND($A12="P0", (DATEDIF($D12, TODAY(), "d") >= $B$4))

Intuitively, one can drag and drop or copy format, etc and the row number changes automatically in the formula. But in the case of the custom formula in the conditional formatting rule, the row number does not change automatically ($A12, $D12).Any solution would be appreciated.
