Convert project dialog box

QUICK SUMMARY: How do I auto-convert Premerie save files to the latest version of Premiere automatically (keeping its original name) and skip this box? [screenshot attached]

Hello!

I'm constantly going back into older files and updating them for clients. Every month, I revisit 10-20 saved files to update or gab assets for a new video. I work with many different clients with hundruds of different files going back many years. So when Premiere updates, and I'm required to go through this dialog box EVERY time I open an old file... and its tedious. I'm not here to complain about the function. I think it's a wise feature for many.

I hope that someone would be able to help me figure out how to overwrite the old files automatically, keeping the same name. So, if I have one file in my folder, it would overwrite that one file with the same name. I have ZERO need for backward compatibility, use ZERO 3rd party plugins,  and ALWAYs use the latest updated Premiere. So auto-converting would have ZERO negative feedback for me. 

I've tried searching for this, but all I get are results around the opposite: people dealing with "saved with newer version" issues. 

Note: The screenshot shows me deleting the "_1" that Premiere ads. I would like to keep the original file name. 

Thank you in advance!!
