We have developed a c# code to import many documents at once from our customer. Unfortunately, when importing, the "Modified on" index is equal to the date of the import. Is there a way to change this index to be the file modification date as in the Windows Explorer?

I know it is possible by creating an other index and populating it with the file modification date but with this option, we lose the automatic update of the index when the user will modify the document inside Docuware. I would prefer to change the system index just at the time of the import if it is feasible. 

Thanks for your help,

Best regards
