API/x2ml add Functional Module Codes

Hello,

is there a way to assign Functional Module Codes with the Capital API or the x2ml API to design object e.g. Connectors, Clips, ... ?

With the Capital API it seems to be not possible, because the attribute "UserFunctionalModuleCodesExpression" is Non Editable (Read Only).

And with the x2ml API (Bridge Processor Plugin) I tried connector.setModule("FM1"); but it wont work.

I know it is possible to add Option Codes with the x2ml API (Bridge In Processor Plugin)....

But I'm looking for a way to add Functional Module Codes with a Plugin.

Thanks
