Visitor log -> search impossible? (no replies)

So I have two widgets I work with closely: Visitor Log and Provider.

I want to search Visitor log after provider-id, so I easily can find the right person/company.

The best thing would be to integrate a button straight from Providers into something like the specific Visitor profile, but I would settle for a search based solution within the Visitor log.

Is any of this possible? I guess it is, but any ideas on how to achieve it?
