Changed Account owner without change the Potential Owner

We have a lot Account(Clients) with their related Potential(Sales). We want to change the Account Owner of several Account but we want to keep the Potential Owner of their Potential. The reason is that we want to track the user responsible of the sales. Now the System(Zoho Crm) is change the Potential Owner alike when we change the Account Owner. Are there a way to avoid this behavior in Zoho Crm and keep the original Potential Owner?
