Export BSS Changes All Mod Dates

I was hoping to make a change to one of the BSS files and then export it to Amazons AWS S3 bucket. I can do that after exporting but most if not all of the files from the BSS export have the same (export date) mod date even when they have not been modified.

This means that after BSS export, instead of Syncing (using cloudberry) the changed BSS file(s) that was modified, the entire project (all files) are uploaded every time. Any workarounds for this?

Not for the system you're using, no. I do my uploads manually so I just have gotten in the habit of keeping track of what has been changed so I know what needs to be uploaded. When you're using an auto upload system, there's no way around the date system that I'm aware of.
