in the stand alone phq users could upload multiple different files and combine them into 1 proof which was very useful. in the integrated model users have to combine assets into 1 document and then upload that if we want to route multiple assets together. Having the ability to combine multiple items into one proof would be very useful.
additional having the ability to merge proofs - if a user uploaded a document, then uploaded a second version but didn't upload it as a new version - having the ability to merge them together would be great, currently you would have to download the latest version and then re-upload it as a new version of the original
