I am looking for an easy way to add an Account specific field into the cases layout.

Right now, when creating a new case there is a entry field for typing in the Account name. What I would like to do is display right below this a "Support Level" field that will automatically be populated once the Account name is filled in. This "Support Level" field would be a custom field in Accounts.

Is there an easy way to do this? I've gone through the exercise of creating custom fields and placing them on layouts ... so I can create this customer field for Accounts ... but don't know how to make it display in the cases layout???

Thanks in advance.
