Introducing "Request sign-off" - an approval flow that requires no set up

Hi,

I'm setting up an approval process. The sign off can be anyone of multiple people. Is it possible to have the notifications go to a security group and any of those members can sign off?

Is it possible to do an "If" statement for the approval group, e.g. if John.Doe submits, lookup his department (e.g. Sales) and email a sales group?

I guess, it is possible to restrict the approvers to a specific group of people?

This might have been answered already. Approval looks really useful for us but it can get tricky in our workplace.
