CMS Grid Parameters
 

In Grid Manager, there are several "presets" like 25-75, 25-25-25-25, 160px 240px etc.

Are there any ways to get finer control of these settings? For example, I may want my sidebar to be 200px instead of 160 (too small) or 240 (too big).

Same goes for the percentage based columns. Also, sometimes we may want more than one sidebar (fixed width stuffs) but that is currently not possible?

Any help would be appreciated.
