How do I use the same underlying query to update/run two seperate charts?

Hi all,

My first post here, so please let me know if I have not done this the right way.

I had a question regarding periscope dashboards and charts. Let's say I have got two charts that have the same underlying query but one chart shows e-commerce conversion for mobile-web and other for desktop-web. Is there a way to 'connect' the two charts so that the query is only run once? The query has dynamic dates, so it will always show data as at last Saturday.

Thank you!
