Message Action Name in URL tracking parameters at email channel surface level
Hi all,
I am creating a url tracking parameter in Marketing Channel surface and want to add the message action name included in journeys. But I need it to populate in the URL following this format: "em-" + context.system.source.actionName.
When using context.system.source.actionName as is, it will show i.e.: Email+-+ "ActionName". Therefore, I'd need to replace the first part mentioned above (Email+-+) by "em-"
Is it possible to treat this type of contextual attributed at channel surface level?
