How to update all ha in one click?

I have several (5) instances of home assistant running.

On a regular basis (when I come back from holidays or want to implements new features) I want to have the last versions of the whole system.

I do not want to update automated update as I do not want to face outages due to this update (in the past even a supervisor update made some instance unstable) so I want to be here when updating so I can fix the issues.

Is there a simple way to update one instance ?

So far I am using this:

ha supervisor update
ha os update
ha core update
for i in $(ha addons | grep slug | cut -d':' -f2); do echo $i; ha addons update $i; done

And then I finish using the web interface.
