Grouping dimension values

Hi,

I want to Group dimension values together. We have a dimension that is called ITproject and it has (among other values) NAV development, Sharepoint development, Office 365 licenses and NAV licenses. Here I want to Group the ongoing COSTs and Group the Project like COSTs, that only appear every now and then.

Thank you for your help.

Magnus

PS. Sorry for the caps here and there but they just pop up automatically.
