In the Style.cfg file (for each isometric style) there is a variable (MAX-LINES) which can be added and defined to limit the number of rows for a report (See below):

REPORT = CUT
    INCLUDE = IE_TYPE=CT_PIPE|CT_BEND	
    COLUMN  = 6:C:CUTID
    COLUMN  = 8:R:SIZE1
    COLUMN  = 10:C:QUANTITY
    COLUMN  = 31:W:IE_DESCRIPT
    GROUP   = CUTID
    SORT    = CUTID
    NODE    = 61
   	MAX-LINES = 5
END

If a report exceeds the maximum number of rows defined, Isometrics Manager will add columns to the right using the widths of all of the columns to accommodate the additional records as seen below:

If the MAX-LINES variable had been set to 4, then another set of columns would be added to the right:
