I am creating a project management site template. This template will be used to create PM subsites in our corporate PM site. In the subsite task list, I want to add a "Work Area" column that is a lookup to a list in the parent site, so that the work areas list needs only to be maintained in one place.
I have seen posts regarding adding WebParts to look at parent site lists, but nothing on how to add a parent site list as a lookup for a column.
Any and all help is appreciated.
