Can I add a unique header line (of data elements) in my mockaroo data file?

I need to create data files that have a unique header line (of 5 - 10 data elements)
and below (the header) line of repeating data elements.
for example:
School,Classroom,Teacher,Grade
StudentFirstName,StudentLastName,MiddleInitial,StAddress,City,State,Zip
StudentFirstName,StudentLastName,MiddleInitial,StAddress,City,State,Zip
StudentFirstName,StudentLastName,MiddleInitial,StAddress,City,State,Zip
StudentFirstName,StudentLastName,MiddleInitial,StAddress,City,State,Zip

is this possible to do in Mockaroo?
Up to now, I’ve been creating the data file of repeating data elements, and manually adding the header line after, but this solution is not ideal.
