In fabric supply/manufacturing business
Let's say the Fabric name is A.
Fabric A have many rolls and each roll have different weights.

Customer ordered 10 rolls of Fabric A. Let's say each Roll Weight - RW.
There should be a field where I should be able to add quantity in front of Fabric A like RW1 + RW2 + RW3.......RW10. And the total of all RW is visible in the default Quantity field. And also the individual RW is also visible which sums the Quantity field.

During dispatching, we recheck if the actual roll weight matches with what is mentioned on Invoice and packing slip.

In the present Zoho inventory system, if we have to add 10 rolls of Fabric A, then we have to add Item line 10 time of fabric A and enter individual quantity in front of it. It wastes time as well as resources.

Please add that. In absence of it, we are unable to use Zoho inventory and Books.
