Installation Note

Good Day !
Gentlemen
I have a scenario in my system like there are 44 Quantities of items in delivery note and I want to prepare the installation note which is installed in 3 stages like 30 Qty 9 Qty and 6 Qty.
While preparing Installation Note I have to retrieve it thrice to enter these three stages
Is there any possible way to retrieve it once and enter all three stages ??
It will be very helpful if someone can find a way for this.
thank you !
