Null handling

Thanks for reading !
It is still a null handling question, my case as below.
Input : FieldA, FieldB
Output: FieldC
In transformer stage, derivation within FieldC
If IsNotNull(FieldA) Then
FieldA
Else
FieldB
As I know, there is handle_null() function within Modify stage.
FieldC = handle_null(FieldA, value)
here, it is only support value ? Can not be a field from input link ?
If yes, any other stage except transformer can fulfill my requirement.
