Automated Working Files

I had a user reach out asking if it is possible to upload an excel file that will allow us to open the file within Sugar, makes changes, and automatically save.  Opposed to accessing the file, downloading, making change, and having to upload it again. 

I've placed a ticket with support who stated this functionality is not available and they've created an enhancement ticket but was wondering if anyone here has the same or similar use case?

Thank you,

Rachael
