How to prevent users from switching price lists in an order?

How to prevent users from switching price lists in an order?

Hi,
I have Zoho Finance integrated with Zoho CRM. My team will be placing orders through the CRM using the Finance module. When creating a new customer I will assign it a price list, I don't want the sales rep to switch to a different Price List, other than the assigned to the customer. I can't find anywhere in Books, Inventory or CRM where I can restrict that. Does anyone knows how to accomplish that?


Thank you
