Hi, 
The approach will be somewhat similar to incremental approach.
In order to reprocess the old date from ADLS, the data should be identifiable [The data could be stored, in folder structure of YYYY->MM->DD> Fille, or file name should contain the date of the file.
This would help to identify the file, then the date could be passed using widget and the file could be identified based on the folder structure or file name.
