Change domain owner & 1-click installs


#1

I’ve been recently setting up a new FTP user per domain out of habit for sites. But for my own personal websites, I want to change it so they’re all under 1 user again. I know how to do it in the control panel, in editing the domain. However, do I need to worry about the stuff I setup in the 1-click installs? Like can I just go in and edit their configs, and they’ll still register in the control panel later for updates?

For example, if it’s unclear. I have:
/home/user1/domain1.com
/home/user2/domain2.com
/home/user2/domain2.com/gallery

Is it easy to set it up to
/home/user1/domain1.com
/home/user1/domain2.com
/home/user1/domain2.com/gallery & all the other installs

by just changing the config files? The reason is I hate logging in as a different user for each domain, and then when I tried to move files between them, trying to deal with permission errors (my linux friend helps me so I change group permissions to move, etc). I just want 1 ssh account and easy access to all my domains, and installs to hold without re-installation of anything. Is that possible?
