[otrs] restore article_attachment from article_plain after table crash

Hi, in my otrs installation i've a partly destroyed article_attachment table. All attachments of 2 month are lost after repair proccess. I saw that the attachments are still saved in the article_plain table. Is there a simple method or tool to "convert" the attachments out of the plain e-mail into the attachment-table? All other tables seems to be ok. So would it be enought to extract them out of the article_plain table and store them in the article_attachment-table? There are only 12 rows - looks very clearly. If there is no tool-script i would write my own in perl. thx Tim
