Change account path / mounting point?

Hi, I am trying to use S3FS for the accounts directories.

Then WHM > Rearrange Accounts, the function works. However, rsync to S3 is extremely slow!!!

Beside rsync, I can use aws s3 sync which is much much faster.


My question is

1. I can move file by my self, but where I can manually change the path info?

I checked /var/cpanel/userdata/<account>, some suspect files, changed info, no works.


2. If #1 is not working, how can i change the rsync command line output by the Rearrange Account function? I can replace it with aws s3 sync , however I think this way is not wise.


Thank you very much!
