Combine Project Name and Planned Start Date.

Is there a way to merge project names that share the same start day into one line?

column.0.sharecol=true

column.0.textmode=true

column.0.valuefield=plannedStartDate

column.0.valueformat=atDate

column.1.sharecol=true

column.1.textmode=true

column.1.value=<br>

column.1.valueformat=HTML

column.1.width=1

column.2.sharecol=true

column.2.textmode=true

column.2.valuefield=project:name

column.2.valueformat=HTML

column.3.textmode=true

column.3.value=<br>

column.3.valueformat=HTML

column.3.width=1
