I'm trying to work out if I can run some SQL scripts to maintain lists at portal level. On my events module, for example, I have Event Category. Currently all the list entries are set to PortalID = -1.
I ran a script to change half of these to Portal 0 (my dev portal).  I then expected the ListController to get only the items for that portal.   
I use this code:
                    listDataSource = listController.GetListEntryInfoCollection("SmartThinker_EventCategory");

to get the items for this list. It gets all the items by that name, regardless of portal. I then had a look at the core stored procs, and GetList is the one that uses PortalID, but this returns the top level list info. The only stored proc (4.5.1) that I can see that returns list items is GetListEntries, which doesn't take in the PortalID, so it will ignore this.

So my question is, how should one retrieve list entries for a list for that portal only. I don't want to use code to filter the list on PortalID, I want to use the core methods that only return the list entries for that portal. Does this exist?
I expected an overload which looked something like this:
                    listDataSource = listController.GetListEntryInfoCollection(ListName, PortalID);

Am I approaching the solution incorrectly? When you make a duplicate list for a different portal, does it share the same name and just have the PortalID different,

eg.

ListA Portal 0
ListA Portal 1

or does it have to have a different name:

ListA Portal 0
ListB Portal 1

I would not expect it to work like this as it almost makes PortalID redundant.

Perhaps one of the developers who worked on this could comment? I am not asking for a UI, but if we can solve this it is a major step forward for portal list-users the world over...

Indeed - There is no UI for lists at portal level for some reason, but I am trying to run SQL scripts to move lists to a portal - if this can be done then I will release some scripts to help users move lists from Host to Portal level, but I have hit a few problems highlighted above.

It will definitely benefit all the Smart-Thinker modules, as well as any other module that uses the core list functionality.
