Custom Query Strings


I am new to Piwik and i have been playing around with this, i tried searching the forum for an answer to this question of mine and i haven’t found a straight forward answer.

Question : Can we generate reports based on query strings ? cs-uri-query is a column in IIS logs, when i import it into Piwik i get all that i need, i did look into custom variables but noticed its easier to get a custom report using the tracking code rather than IIS logs. So how does one generate a report based on the query strings from IIS logs ?

PS. I noticed someplace this has to be a new feature in , is this true ?
