Dataflow Incremental Refresh Update Specific Partitions

Thanks for the link, v-janeyg-msft 
The Incremental Dataflow sits between an initial Dataflow and the final Datasets.  The Initial Dataflow is import a JSON file and transforms it into a couple of Tables.  These initial dataflow tables are limited to 30 days of activity.  The Incremental Dataflow is working as designed.  Each day is reads the last 30 days of activity, but only updates the last 14 days.   My Incremental load contains data back through Oct 2021.  If was hoping to have the flexibity to update some of the old partitions to add, remove or replace them.
