You can’t do order line automation with products. Create a order tag group with all order line automations map it to all products and turn auto select off. Use products for ticket automation like open drawer.
Use Order Tagged event to build your automation for order line commands.
The effect will be when order selected your POS menu on right changes to Order Line commands. Price Change, Void, No Tax, etc. Ticket based commands or system commands can be the actual menu and products/quick menu. You could even use Suffice/Prefix for reasons etc.
