While in a group page, you can select the item type to filter on (maps, apps, layers, etc...). Is it possible to to select multiple types for your filter? I'd like to be able to view Apps and Maps at the same time. I tried formatting the link to include 'focus=maps&focus=apps', but it just returns all items in the group.

Selecting the Maps filter formats the link like this:
[xyz/home/group.html?id=65e50fc1fc9548d783cb95cbebfb724a&view=list&sortOrder=asc&sortField=title&focus=maps#content]
I tried this and it didn't work:
[xyz/home/group.html?id=65e50fc1fc9548d783cb95cbebfb724a&view=list&sortOrder=asc&sortField=title&focus=maps&focus=apps#content]
Any help would be much appreciated!
