Is there any way to stop the notification from dissapearing when you close the maemo notification window for an SMS?

When you close the maemo notification it does not mark the sms message as read in conversations until you actually open the conversations app and read it there?

More often that not I find myself closing the maemo notification only to forget that I still have the new SMS message sitting in my inbox in the conversations application which I need to reply to...

If the call notify notification would remain until there are no unread sms messages in the inbox it would be great - or if this was a configurable setting.
