It is possible to create reports via the API if needed.

//initialize a new report set which will contain the report 
ReportSet rs = new ReportSet();
 
//add tables
                JoinedTable jt = new JoinedTable();
                jt.TableName = "[dbo].[Orders]";
                rs.JoinedTables.Add(jt);
 //add fields               
                Field f = new Field("[dbo].[Orders].[ShipCountry]", "Ship Country");
 
                rs.Detail.Fields.Add(f);
//add filters
                Filter filter = new Filter();
                filter.Column = "[dbo].[Orders].[ShipCountry]";
                filter.Operator = OperatorTypes.BeginsWith;
                filter.Value = "U";
 
                rs.Detail.Filters.Add(filter);
