Server-wide quests

[JrFaust]

I quote...
"Server-wide default quest in: $EQEmuDir$/quests/default.pl"
"Zone-wide default quests in: $EQEmuDir$/quests/zonesn/default.pl"

With that in mind can one name a server-wide quest $EQEmuDir$/quests/BillyJoBob.pl and then have a script run BillyJoBob from zone to zone and still work or does one have to have a BillyJoBob.pl in every zone?

Also can one make a pl file for there character and have script for them selves?

For example if I wanted to gather to myself all my minions in a zone on spawn could I?
I'd test this myself but I'm at work and I just got the idea.

Thanks for your time,
Rob
