[TYPO3] TT_news: datetoarchive when two contenelements on 1 page

[H.E.Weenink | Aristo WebDesign]

Hello all. (and I ask here, because no response in tt_news maillist)

I have two plugins on 1 page. And they should have different datetoarchive. 

I know how to do this with templates if on 2 pages, but how to get this done
if both are on 1 page, using templavoila? 

Regards, Eef
