Can this be configured to only sync a certain folder?

I would like to be able to copy only what is in Bucket1/folder1 to Bucket2/folder1.

Can this be modified to do that?

The code would need to be modified.

In index.js, you would modify the processRecord function such that you would compare srcKey to your desired folder. If srcKey does not start with your desired folder(s), then abandon the rest of the copy process.
