How can I tell users to easily find that number?  There is certainly a better way to obtain the jobid than by translating between %i and %A using:

You could always just use overwrite squeue with alias which you put it
in /etc/profile.d or where ever you have your global setting, although
this could also potentially cause some confusion.
