Is it possible to have a formula somehow on cell A1 that checks as a conditional if A1 is empty?
Obviously, the default way I'm getting a circular dependency error. However, I figure some formula might be (?) smart enough to see that when A1 is in the conditional (and not a part of the new value) it's not really a circular dependency after all.
So does a function like this exist?
if cell itself is empty -> fill it, otherwise do nothing
