Canvas Max Width

[BF_LL]

With the popularity of ultrawide monitors, it would be great to have the ability to set the max width for the canvas in Power BI.  Fit to screen doesn't quite work because we have pages that require long scroll.  Currently, we are forced to use Power BI Embed, so we can control the max width of the iFrame.  Would be great to set at report canvas level, so that it also displays nicely in Power BI Service for various monitors' aspect ratios.
