Can we remove 2nd approver from voucher workflow through Monitor Approval Page

Hello,

We are on PeopleSoft 9.2. We have a custom voucher workflow where approvers are assigned based on roles, GL accounts etc. There is one voucher which is currently pending with 1st approver and the user is requesting to remove the 2nd approver from the chain. When I go to the Monitor Approval page, as an administrator, I don't see any option for me to remove 2nd approver. There is only a (+) sign which means I have the option to add an adhoc approver.

When does the admin see (-) sign in the chain ? Is there any other way to remove the approver as I don't see any option for that in the Monitor approval page.
