Background Export of Pages and Collect Export from Alternative Location

Problem Definition

For long running Space Exports using Content Tool Export, would like the ability to navigate off the Export Progress Page and still be able to gather the file(s) when the Export completes.
Currently if you navigate away from the Export Progress page (either clicking on another link or due to session timeout), there is not a way to collect the Exported File or be notified if it completed.

Suggested Solution

An option to perform an Export in the background and then present a notification or path to the file's storage location where it can be collected

Workaround

The Export Progress Page needs to remain open in a Tab or Window so that the file can be collected when complete.
