Hi is there a way to renew or set export parameters specifically for a text block? I would like to change the date depending on which subtree I'm going to export. However the following way is not working.
#+DATE: 08-11-2011
* level 1
#+DATE: 12-11-2011
* level 2
#+DATE: 15-11-2011
trying to export only level 1 would still result with 15-11-2011 as date.
Any sugesstions? I tried properties blocks but had trouble with them too.

Thanks a lot
Torsten
