Considering the current exceptions capability in ASM, you're looking for a "workaround 'ish" solution. There's no built-in feature set for this level of granularity. Your equally good long-term scalable solutions are

 

  • a secondary "Relaxed Policy" matched for a specific Source IP address in LTM,
  • or an "Unblock iRule". In case of more exceptions - preferably built on top of a LTM data-group.

How likely you consider a scenario of having similar exceptions for other Source IP addresses? If you're rather positive, you're definitely better off with the "Unblock iRule" solution. If you need a reference, look around the codeshare. If you're still stuck, feel free to ask a fellow comrade write the whole thing for you.
