Copying/Importing Bins from one project file to another

Hello there all: I can't seem to find anything in the forums which addresses how to quickly copy a bin (and all of its contents) from one project file to another? I'm working with Pro 11 and it would be very helpful to copy and paste a bin from one project to another to save time. Right now I have to re import everything when I start a new project and it can get quite complicated/time consuming since I often have multiple source files connected to a bin. Anything you can offer is most appreciated.
