"Stitching" Together Material -or- Multiple Sheets for 1 Oversized Sheet

I would like to use this program to order insulation in bulk 24"x48" Sheets. I've quantified all necessary material in a CSV File and imported it into the program. Now my problem is that the program is telling me a I have "sheets" larger than my stock size of 24"x48" Material, which is correct, I do. I'm looking for a way to tell the program to cut these large sections out of multiple sheets of insulation.

For Example: I have a required sheet size of 40 7/8" x 62 3/4". I know I can achieve that by using as 2-3 sheets of 24"x48" Stock Insulation, but is there a way to tell the program it can do the same?
