Direct Query Less than 15 minutes

Hi,

Is it possible to reduce the minutes of refresh in Direct Query method ??

I would like to use a Dashboard with the option of "refresh Dashboard tile" But it does not give me an answer because I need the refresh at the minute level (not every 15 minutes) !!

I am currently working with the plugin (Super Auto Refresh Plus) knows refresh the browser, but it does not seem the most professional that basically all the page refreshes, and not only the object..

Do you have any idea for me ..?

Thanks,

Alon
