Display 1 or 0 based on multiple conditions. If one is accomplished, stop the second one from running.

Hey guys

I have another problem if you could please help me, thank you. I have this setup:

I want to display 1 in column M for the first item that has the condition Yes, column K is a drop down with Yes and No. I don't know how to stop the second formula to run if the first one is accomplished. I use this now:
=IF((AND(K1="Yes", K2="No")), "1", "0") and =IF((AND(K2="Yes", K1="No")), "1", "0")

When I pick Yes, M turns into 1, but if I pick Yes for the second one, both turn into 0 again. I'd like to keep the first 1, and all other duplicate items that get Yes to remain 0. Is it possible without scripts?

Thank you
