Hi @NITIN_B_PARIKH - what Mike suggests is one possible solution, mapping to an uphill target in the SOPT hierarchy. But I agree that it is not quite clear why these two were made non-standard while all their siblings are standard. There are three more non-standard concepts in SOPT but they seem to deserve that fate as they are flavors of null. Let’s see if there is more input from the community and let us create a github request that we then can follow up and keep tracking!
