[FEATURE] storageManager dynamic url endpoints

FEATURE REQUEST

SPA approach for dynamically loading and storing utilizing the storageManager urlStore and urlLoad config options. It would be GREAT if your code checks if it's a function, not assume it's a string literal defined finitely, explicitly, at time of initial configuration (page load). Changing the config values during runtime has NO effect on the predefined storageManager.

Or perhaps add the params configuration object to the urlLoad as well. Shouldn't params defined in config be passed to BOTH load and store?
