Background to my question:

 

Sometimes I need a grid without Source, just using the Filter Box (selection of items based on multiple criteria).

 

However it would be nice if I can add items to this grid describing what's happening with the grid which stay there after refresh.

Since the Source is empty, I cannot use the auto-assignment of field to TLI. What I have done is create a field with the exact name of the Grid to be used in the Filter criteria. The field is in the grid as well, and currently I have to check it every time I create an item to ensure it stays there. This is not that bad, but then again we have the field ItemHomeGrid. So now I can make the item favorite which automatically populates the ItemHomeGrid field, and then I can use a row equation to set the Yes/NO grid-name field to true, so effectively I can do without additional field in the grid, but have to mess with the favorites.

 

So is there some inherent difficulty in having the ItemHomeGrid populate directly after the item has been created?
