Can I use a report Shared column as a grouping in the report?

Hi, 

I have a shared column that I would like to use as a grouping in the report. The shared column text mode is below:

column.0.linkedname=direct
column.0.namekey=FDN DA Project Type
column.0.querysort=DE:FDN DA Project Type
column.0.sharecol=true
column.0.textmode=true
column.0.valuefield=FDN DA Project Type
column.0.valueformat=customDataLabelsAsString
column.1.displayname=DA Request Type
column.1.linkedname=direct
column.1.namekey=Assistance Requested
column.1.querysort=DE:Assistance Requested
column.1.textmode=true
column.1.valuefield=Assistance Requested
column.1.valueformat=customDataLabelsAsString

Is this possible?

Thanks

Cathy
