i have figured out how to add a column to the sheet index that reflects the revision if the sheet has a revision. now i would like for the index to reflect multiple revisions if said sheet has multiple revisions present. an example would be that we have revisions for our county submittal and revisions for owner changes at the same time. county is designated with a number and the owner is designated with a letter. so sheet A1.1 might have county and owner revisions on it and in the sheet index i would like to see both listed.
