Restrict contact lookup to show only contacts related to account in case object

Is it possible to filter out only contact related to an account in a case object. When a case is created from account, it has the account field in case populated with the account name/Id. I want to select contact and the lookup should only show contacts related to this account. Is this possible?
I have a filter criteria case: Account Name ID Equals Contact Name : Account Name : Account ID. Event then it is not working.


Create below filter criteria on Case > Contact lookup field 

Case: Account ID equals Field Contact Name: Account: Account ID

Very usefull answer!
I just reformulate like this :

On "Case / Contact" lookup field, modify and create the filter :
Field "Case / Account ID" [equals]  Field "Contact Name / Account / Account ID"

How do I do this on a custom object. Contact Name doesn't exist.

Did you get any solution @Chris-ARI?

From what I've found, we can't create filters on Custom Objects. Has anyone found otherwise?

How could we set up this filter for when the account is in a heriarchy and the contact is created on the parent (or top parent) account?
