Custom layout and or custom stylesheet file for the dashboard

Hi there,

Is there any way that I can customize the current layout of the dashboard and or the style-sheet(s) that the dashboard is using?
I’ve been looking for this feature in the docs and other topics and trying things for about 2 hours now but I can’t seem to find anything.

I would like to know whether this is possible or not, and how I should do it.

Thanks.
