When I'm on a VirtueMart category page and select VM Categopry as dynamic content and VM Sub Categories as multiple items source it would be awesome having "ordering" option. Same for other sources.
Sometimes we need alphabetically, or latest or using the manual order, etc.
We have verified that additional argument options are not feasible for multiple item sources. This is because the arguments are managed solely by the element in which the dynamic content source is integrated.
