Approval based on Field Selection

Approval based on Field Selection

Hi,
We have a Access request (service request) form for ERP application, we would like to route the approval based on the Module selected in a pick list (additional field) eg. Module = Finance : 1st Approval = CFO

The other approvals will be fixed and predefined with name.

These approvals do not have to be on roles, we can define user names as well.

Possible? Please assist
