SigningHub allows you (Document Owner) to rename your documents package as long as its status is either "Draft", "In Progress" or "Pending". If you do not rename a package, the package name is automatically determined based on the names of all the documents in it, separated by a comma. SigningHub will keep appending the package name in the same way (i.e. document name and a comma), upon adding a new document in it. Once you rename a package SigningHub will stop appending its name further, to add new documents in it.
Click the "Documents" option in the navigation panel.
Select the desired document and click the "Rename" button in the information panel.
Specify the new name of your document(s) package, and click the "Save changes" button. The package will be renamed accordingly. However the names of documents in the package will still remain the same. See details how to rename a document.
