Approvals in RTC - One of Multiple

Hi

I am new to RTC.

I have successfully configured a workflow with an approval stage which requires all approvers specified to set their approval to Approve before work items can be processed to the next stage.

When a work item is ready for approval, one of a number of managers is required to approve the task - I don't mind which of the managers it is, I just want the first one to approve the work item.

Is it possible to configure approvals so that I can specify multiple potential approvers, only one of whom is required to carry out the approval?

Many thanks in advance
