What we need to solve this is a cell aggregation dependency function in the database. Where we define a column and a query that will be used to define the values in the cells of the column. The database would use its planer to figure out what the dependency's are and update the cell every time one of the dependencys are changed. That dependency thing is very complex but very necessary. If you dont have it you might as well just make a normal view.
