Loop to create multiple Flat Files

I have a table with 2 million recs. I have used OLEDB source SQL command to split the recs into 5 batches.

Example 

select * from table where number between 0 and 100 -> result of this stored in flat file with name 'File1.txt'

select * from table where number between 200 and 300 -> result of this stored in flat file with name 'File2.txt'

and so on.

i have created a Data Flow Task -> within that I have multiple OLEDB source and Flat File pairs.

Currently have 5 diff flat file connection and it might increase to 20. how to avoid this and use single connection to create all files.

Thanks in Advance
