Be able to remove shipping fees for physical upsell products

I have events and classes that I offer the choice of project or supply materials as an upsell option for people to create during their booking. There does not need to be shipping charges on these products for bookings. However, I cannot remove the shipping from the actual product since I also sell these items online and do ship them out to customers. Please configure the option similarly to what you already have for bookings to not require shipping. It can be a blanket setting in the app or an optional setting to choose on our end. Thank you.
