If, and Then... Google Sheets

I have UPC codes in Column C, if they are duplicated, column D shows "TRUE". If the issue has been noted a drop down in column H is changed to "Yes". All of this functions as needed.

What I need now is, if D is "TRUE" & the first instance of the duplicate has been noted, I need this to be shown in column I. Is there any way to make this happen? Or alternatively, if "Yes" is selected in H on the first instance of the duplicate, it is auto-filled into all instances of duplicates. Any help will be greatly appreciated.
