This is extremely useful and critical for users who are storing thousands of documents based on a single field for Autoindex (Voucher number, for example).

Since Autoindex occurs at the back end, it is difficult for users to say whether they encoded the correct voucher number or not.

By allowing Autoindex to execute prior to storage, they will then be able to immediately see if the Autoindex results match the document being viewed.

I suggest the feature should work similar to the "Autofill Indexing" feature. Click the button and then the Autoindex job will execute. It will then fill up the indices with the results.
