Odoo 14.0, CE.

Provider takes 2 days to deliver any product. If I send a PO on Monday its all good, odoo will say I'll receive it on Wednesday (2 days later), and the delivery happens on that day, but if the PO is sent on Friday... Well, odoo thinks I'll receive it on Sunday (2 days later), but that is not the case, since we close on weekends, and I'll receive it on Tuesday (2 working days later).

How can I settup this behaviour?

Thank you.
