Different grouping for Line and Column values in PowerBI Line and column Combo chart

Hi,

I'm using Line and stacked column chart. It is supposed to look something like this:

I need to group the line values based on UserType( ExternalUser,FoundryUserFoundry etc) and group the column values based on Geo ( US, APC,Europe etc)

Currently I'm able to group the column values based on Geo and line value gives the aggregate based on Geo, I'm unable to add a seperate grouping for Line values.

My chart looks like this:

 Is there any way to add a seperate grouping for line values?

Thanks in advance,

Bhavya
