Custom Grid Dimensions (snap-to) for Panels

Hi - I see the configured grid has a fixed size (24 columns wide) - if you wanted a custom grid width to snap panels to is this possible? e.g. to increase the number of columns to a higher number.
The reason being we would like 10 single stat graphs to fit across but 2.4 as a size is not supported. You can manipulate the dashboard json but when the dashboard is edited manually it resets panels to whole number sizes.


I am also very interested in this. Anyone able to provide some insight?

Likewise, but I would be interested in adjusting size to browser window, and also content. For example, if I had a panel with varying numbers of rows selectable by a drop-down, could the panel grow in height based on rendered content?
