In bash you can use two special characters regarding hostname:
hto get host name up to the first dotHto get full host name
If you want anything else you need to make your own version for example with HOSTNAME variable:
[root@digi ]# HOSTNAME=digi.master01.usa.com # this should be set automatically by bash
[root@digi ]# PS1="[u@$HOSTNAME%.*.* ]#"
[root@digi.master01 ]#
