Pack Sizes and Weights

Hi, can you explain, this information is by the product, how do you want to display this info?

Some of our products are fairly bulky and heavy, so we want our customers to know before they come to pick up that they will need to bring a suitable vehicle.
Would like the email to state:
– the total weight in kgs of all the items – either added together or individually listed
– and size that the items are – this may have to be per individual line item (not sure if this can be a total calculated for multiple items purchased?)
