I think a feature that allows the leader quantity to only display selected items or items visible on the sheet should be implemented or even a way to simply override the quantity like you can with the item number. while keeping the quantity the same on items list/BOM
This is useful for things such as panel creations as when the assembly drawings are done it will show what parts are needed for which specific instance/page.

E.g like this (taken from AutoCAD not inventor but for demonstrational purpose) item number 99 shows how many are used in that instance not the total in the model
