Just watched the video at this blog https://communities.bentley.com/products/microstation/b/microstation_blog/posts/like-v8i-you-ll-love-connect---sheet-tracking-and-ordering
What I want to know is can Sheet Index cope with a drawing no. like "11827 - WMS - ZZ - ZZ - DR - A - 10005 - S2 - P1", which is based on BS1192 drawing numbering?
I'm guessing that as there is no response then either it's still holiday in Bentley land or this is not possible. I'm guessing not possible but perhaps the writer of the blog could confirm this, especially as the blog does say "You can customise the sheet numbering as per your standard."
