Override "Show Discount Details on Invoice" using a Manual Modifier

Hello everyone,

I am working on turning on the "Show Discount Details on Invoice" feature (within the "OM System Parameters") in a 12.1.3 instance, so Modifiers will be interfaced to the AR Invoice as separate lines.

However, the client would like - in case of Manual Modifiers (for price changing purposes) - to Not have this modifier interfaced to AR.

I remember that this option was available in other releases (not sure which one):

I would like to know if there's an option to override the "Show Discount Details on Invoice" system parameter within a Modifier Line, so the client will be able to change the price on a Sales Order line (regardless of the "OM: Discounting Privilege" profile) without using a manual Modifier, or maybe to override this OM System Parameter for a specific Modifier Line (like in the above screenshot)?
