Split coupon code by website

I’m having a issue on magento 2.3 multishipping. I’m with 2 products from different stores on quote, and a coupon code added(who match the conditions only by 1 store) when multishipping starts, magento creates 2 shipping address, one with discount(because match with the conditions), and the other store comes with the normal price(without discount because doesn’t match with the conditions of coupon code) I need to split coupon discount between 2 websites even if he doesn’t fulfill all the conditions at some point in one of the stores.
