Make //sel extend persist through sessions and restarts

[MinecraftAdmin]

What feature do you want to see added?

I almost exclusively use //sel extend for ease of use and peace of mind. It is quite frustrating having to type //sel extend everytime I relog or server restarts.

Please allow that selection method to persist through sessions and reboots!

Are there any alternatives?

A workaround is making a script that executes //sel extend for me everytime I log in, but a native feature would be much cleaner.

Anything else?
