Looking for a way, other than a million assemblies, to automatically add certain items to a sale. Like the 'Call to Recycle' 15$ battery fee with every e-bike sale. A shop/environmental fee with many labor SKUs.

You can currently remind a cashier to do this through 'Additional Messaging' area in an item but it ends up being just another window they click thru quickly without reading.

You can also do it to a degree with an 'Item Modifier' but this is added to the base price and not listed as a separate line item.

I'd like to make this idiot proof for our staff.
