I have a group of clients who have very similar controls. Can I copy the work I have done under controls (B section) from one job into the others then just amend for any small changes?
A. You can't import content from existing jobs, but you can create one job with the section completed then duplicate it for the other jobs. If you are already past that point you will have to copy and paste the information across. You can have both jobs open simultaneously on separate screens say so this is not as difficult as it may sound.
Another option that could perhaps be to create a kind of a "master job" for the group and do the B section in there for them all, then convert those pages to PDF and upload them into the individual jobs as attachments rather than completing the full B section pages for each job.
