pbulk additional package

[Fekete Zoltán <fekete.zoltan%minux.hu@localhost>]

Hi There,

I use pbulk in a chroot to bulkbuild my selected packages. I use 
limited_list.
However sometimes it is necessary to add one more individual package to 
the already built package collection.
Is there a way to do this, or should I rebuild the whole collection from 
scratch?

Thank you,

FeZ
