Its been awhile since I used CM.
I have a new client that I just added and gave them their own login and access to their account with marked up pricing. When I log in as them I see MY logo in the upper right corner. I remember being able to brand a client account so that when they login they see their own logo. Is this possible?
No, this isn't possible. The only way you could set this up is if you actually set up a separate account for your client, sorry.
