Number of items on a plate#795

I would like to enter how many items are on each print plate and the total number of items I need to produce.

For example:

• Each plate contains 10 items.
• I need 130 items in total.

Each time a plate is completed, the system should automatically subtract 10 from the remaining total.

There should also be an option to adjust the completed quantity if any items fail. For example, if 2 items fail, I can change the completed amount from 10 to 8, and the system will subtract only 8 from the total.
