Hi Janelle!
This may take some Frankensteining depending on your columns but should give you the general idea. This code combines column 2 & 3.
FIRST Replace your last line with: valueformat=customDataLabelsAsString
THEN add the following below:
column.2.valuefield=USERNAME
column.2.linkedname=project
column.2.valueformat=customDataLabelsAsString
column.2.displayname=NAME
column.2.namekey=view.relatedcolumn
column.2.textmode=true
column.2.sharecol=true
column.2.namekeyargkey.0=project
column.2.namekeyargkey.1=USERNAME
column.2.querysort=DE:USERNAME
column.2.shortview=true
column.3.displayname=ENTRY DATE
column.3.linkedname=project
column.3.namekey=view.relatedcolumn
column.3.namekeyargkey.0=project
column.3.namekeyargkey.1=ENTRYDATE
column.3.querysort=DE:ENTRYDATE
column.3.shortview=true
column.3.valuefield=ENTRYDATE
column.3.valueformat=customDataLabelsAsString
