Large raster images make opening file from ProjectWise Explorer very slow. Is there a way to tell ProjectWise to ignore the raster files until the OpenRoads / MicroStation file is open?

If I anticipate having to work from home in a specific OpenRoads Desinger file that has large raster attachments, I can export a managed copy out of ProjectWise before leaving the office and there is no problem. 

However, I don't always know ahead of time that I will need to open such a file from home. Those large raster images attached to the file make opening it from ProjectWise painfully slow when I'm working from home.

It would be great if I could somehow tell ProjectWise to ignore the raster images until the file is open and then I could manually update them if needed.
