Grid or Grid2 fit to specific size

[waxor]

Hello, I want my grid to fit within a specific area no matter how many people are in my group, currently there is space for 30 people in my box, but I want my grid to resize frames if there are less than 30 people in the raid or if there is more. - This is mostly so it looks good both in flex 30 man and in mythic raids.. However I also want it to fit with 40 people for world bosses and battlegrounds if possible.

Is this possible with either Grid or Grid2? - Currently I'm using Grid2, but I am willing to switch to Grid if it's only possible with that.
