Reverse order of RSS feed postings on boards.

[tyranny]

I have search every possible combination of terms to find an answer to my problem, so if I missed it forgive me.

Basically I am looking for a way for the RSS feed to either use the date from the feed as the posting date or for it to post in reverse order so the older rss items get posted before the new ones at the top.

I have a few feeds I would like to add and "catch up on" but if I add them and let them run it will put the oldest items at the top of the forum and the new stuff at the back. I tried it and had to go through and edit the dates on all the items (which kind of defeats the purpose I guess of automatic).

Does anyone know if this is an option I am missing or point me in the right direction?

I appreciate any help anyone can give.
Thanks.
