[pmwiki-users] Pagelist sorting accross groups

[Pico Ben-Amotz]

Is there anyway to cause a pagelist to sort across groups using order=
and a page text variable?  I have a PTV (called NextDate) that appears
on pages in more than one group.  I would like to have a pagelist that
returns all pages sorted by the NextDate.  Right now, the pagelist
returns a list that is sorted by groups before being sorted by dates.
