Restrict what other project managers can see on the approval notification

Content (required):

Hi all,

We have enabled the project manager approval workflow on our expense system, and it works fine. Also, when having multiple projects on the same expense report, hence, having multiple project managers approve the expense report is functioning as well. However, all the project managers have access and can see the other lines that not should be available to them. They should only be available to see the lines on the expense report notification approval that is of their concern, hence, accounted on their project, and not the other lines that are accounted on other projects in the same expense report.
