After clicking the Manage link on the Manage Opportunities page, you will be directed to the Manage Opportunity page. Click on the Single-Project Package tab.
Click the Continue button under the Manage Single-Project Packages header for the package you wish to continue working on. If the Single-Project Package has already been published, it will appear in the Records table. Click the Modify link in the Actions column to modify a published single-project package. The data fields and steps to modifying a package are the same as creating a package, so more detailed information about the application package details are available in the Create a Single-Project Package.
Remember, modifying a package is separate from modifying a synopsis since they are two separate components of the opportunity, so the Updated Dates for synopses and packages are not connected.
If you need to change the form package template, refer to the Change Template for an Existing Package help article.
