saving and loading a session via config file?

What would be the recommended steps for saving a session and loading it later? What I am doing is saving the view config into a file, and then next time I start HiGlass, I click "edit view config" and paste the contents of the previously saved file.

Is there a more streamlined way to save the config and have the local server load the saved file by using a filename or file ID in the url, similar to the example below?
