Hi--
Yes, LOGic has a good bulk updater.
https://youtu.be/5d5gyJVFQEs Please like/subscribe to our youtube channel.
However, I do not believe this is the best way to go about it. There is a SELECT CRITERIA box in the Upload to LOTW form. If you want to reupload everything since a certain date, click the ... button and fill this out.
In the ADIF EXPORT OPTIONS popup that appears, uncheck the box that says "Do not export if already uploaded to LOTW."
Let me know if any questions.
Tnx & 73,
