Hi Jenny,

Thanks for your post.

There isn't a feature in the software to achieve this as such. We'd normally recommend making a manual calculation and then adding it as a payment, there's more information about setting up payments here:  Create and manage payments

You may like to request this feature on the product Ideas Board
