Incremental Refresh - Can you change parameters and repull data

I wanted to do 2 or 3 partial data refreshes to slowly build up a historical dataset, slowly increasing the rangestart and rangeend until the full dataset had been pulled.

After testing and doing, I realized that the RangeStart and RangeEnd were finalized in the initial upload to the service. Once they were set and published they could not be changed. No matter how my other date parameters changed the newest incoming incremental data would only be in the time horizon established in the Incremental settings of how many days to go back.
