Yes, there is such a feature.
You can export a LAR file from Workbench - just right click on your process. It contains all the things you need to reconstitute it on the other end, including process, forms, and non-standard components.
At the other end, you import it using Adminui, rather than Workbench.
I guess the reasoning is that developers do the exporting, and administrators do the importing into production. In practise, it's a bit confusing that it's not orthogonal, but it does actually work quite nicely.
Note that you do have to set up any end-points again if necessary, and possibly set security/permissions.
