I suggest using the terminology of first responder [1] and not focus. 
The former is likely more aligned to what you are asking for and the 
later is a view drawing concept.

I think it may help to step back and better outline or restate what you 
are trying to achieve. If you do that we may be able to help you with a 
solution.

So what would you use this information for? etc.
