cut list quantity

I would like to know if it is possible to have a new Quantity column in my cut list which will multiply the standard quantity column by a number which is definied by custom properties?

Lets assume we require 3-No beams whicha re all the same length with the same end plates either end.

The cut list will show that we require

Beam -1 reqd

End Plate - 2 reqd

I would like to be able to have the cut list show that we will require three of each as below

Beam  - 3 reqd

End PLate - 6reqd

Any help would be appreciated.
