A question to pick your brains!!

Currently, for our Engineers to "Check Stock Out" of our Warehouse, I have built a FS Mobile Flow which firstly allows them to choose from a list of Stock Locations (Record Choice Set as Radio Buttons), then navigates to a Record Choice Set of Product Items, where the Location ID is the ID from their first choice.

This Product Item record set is display as a Checkbox group. They can then select multiple Product Items. We grab their IDs and then loop through in a screen flow, allowing the engineer to select the quantities that they are taking out. At the end, we create the Product transfer records to move the Product items t the Engineers location.

All well and fine. It works. But....

The experience of it is not great. As our inventory list grows, the number of Checkboxes grows too, making it tricky for an engineer to navigate through the list of the entire stock pile we have and it is taking them 20-40 minutes to remove stock.

What I'm hoping to build is some sort of "Crate" or "Batch" number system, whereby our Stock Manager could go to a Work Order (On Desktop) and go through a screen flow where by on each Work Order Line Item, they are presented with Stock Levels per Location, and they select which Location and Quantity, they are taking stock from. This could be performed for one or multiple Work Order Line Items. This would in turn, create a new sequential number for a "Crate" or "Bundle" of Stock, which our Engineer could be given. they Arrive to the warehouse, collect their crate of parts. Open up the FS app, pop this "Crate" number into a Flow, which can then go about making the Product Transfers from the respective location IDs to the Engineers mobile location ID.

This would obviously make like a hell of a lot simpler for our engineers.

Has anyone here built anything similar?

Thanks
