I'm  wondering if you would be available to assist me with creating a workflow approval process that would allow multiple approvers to sign off on a change control ticket such as:

Ticket gets submitted goes to approver #1, approver #1 gives the ok then the process goes to approver number 2 for the ok, and so on to 3 and 4, before final approval is given.

How can a process like this be setup within the change workflow feature?
