POS email cart to customer: remove discounts before submit !?

[zrf1]

When trying to email the cart to the customer where discounts are applied automatically, an error message shows up saying that all the discounts have to be removed using the more actions button, and when doing so, the cart can finally be sent.
Is this a limitation of the POS cart/checkout feature? Any way to keep the discounts? Or an alternative to at least add the discounts again when opening the cart?
