Creating credit using P420111 results in opposite sign

I create an SQ using line type CK (Inv Interface Y, Reverse Sign Y).  After save order my Quantity -10

I create CO using P420111.

- version of P4210 called has order type = CO and line type CK

CO after generate order is positive 10.

I assume this is because the Reverse Sign of the line type is being looked at as part of P420111.  Is this functioning as designed.

Reason I ask is we create CO both from SQ and manually (like from History).  We would like to have all CO have the same line type of CK.  But I don't see how this is possible if I'm using P420111.  Unless of course my SQ is a positive quantity.  But that is confusing and counterintuitive for users because they are Quoting a Return.
