Add days to a date picker and have it save in a new date picker (excludes weekends and holidays)

[LostInTheSauce]

Hey All,

   I am looking at add days to track when a document is due however I need to exclude weekends and holidays (Holidays are kept in a SharePoint list).

Example:  Flight returns on July 1st, 2020.  It is a requirement that 5 business days after that, the employee is required to submit a report.  I need the due to column to equal July 9th, 2020.
