ProjectWise and Sharepoint - Document Check In

Is there a setting within ProjectWise Web Parts/SharePoint that will prompt or automatically check in a document?

I have a project that is using ProjectWise Web Parts from a SharePoint site and have several users opening documents but not checking them in after they close the document.  To there credit they do not know that the document is not being checked in nor do they remember if I tell them.

Anyone else have this same issue or have a solution?
