Meta Chain in Cameo Magicdraw SysML

Was hoping someone could give some guidance on this. I am looking to meta chain (unless there is a better implementation) from a whitebox IBD connector to the item flow element to create a custom column with details of the item flow. Not sure how that works or where to navigate from the connector to the item flow data. Any guidance would be appreciated.
