Grouping Asset Bundles

[adoerler]

Hi,

I'm on a point where my combined css grows above 278kB which causes issues in IE9, as this stupid browser cannot handle stylesheets bigger than this limit (see: http://stackoverflow.com/a/23241583).
Luckily this limit is per file basis, so I though the solution will be "Grouping Asset Bundles" (http://www.yiiframework.com/doc-2.0/guide-structure-assets.html#grouping-asset-bundles).
As far as I understand the process of building the grouped assets is either manually (unsing grunt or similary component) or by using the AssetControllers Console command.

Are you familary with Grouping Assets? Do you think this could also be done using your great yii2-asset-auto-compress extension? This would make things pretty easy (for me ;-)

Kind regards and thank you for your help
