Question

1C-Bitrix

Good afternoon!

There are two warehouses:
1) Norilsk;
2) Moscow.

Eagle client. Orders 2 items, they are both in different warehouses. Delivery from Norilsk to Moscow - 4 days, from Moscow to Oryol - 2 days. In addition, one more day is needed for assembly. Is it possible to somehow do it in Bitrix by regular means or add. modules so that the visitor is shown the delivery time of 7 days (taking into account the movement and assembly)?
