ResourceFirst allows you to copy assignments from a project to one or more projects. You can copy a single assignment or multiple assignments at once.
To copy a single assignment, highlight the row you want to copy by clicking in any non-hyperlink field. Then click the button in the upper left. This will open the following dialog, which will prompt you to select your target project.
Choose your target project and click "Copy" and your assignments will be copied.
To copy multiple assignments at once, follow the same instructions as above, except highlight multiple assignment rows to copy by using Shift-Click and selecting multiple rows.
