Is there a way to request re-approval when someone updates sales agreement?

Hello,

I'm preparing for CRP, and sales agreement scenario is like below.

Enter agreement --> submit draft --> manager's approval --> customer's approval --> create release --> update agreement --> manager's approval

Client needs approval after agreement modification, but an agreement get active, it never proceeds to re-approval flow.

Does anyone have a solution/workaround for this?

Regards,

Yuki
