Send WF proof from photoshop file with artboards

Description -

I want to be able to send a file to proof but the way our organization works is with multiple artboards in one file. This would streamline a process by eliminating a step of export and mockup. 

How would you like the feature to work -

Currently, I run into an error when sending the proof to workfront with multiple artboards. So I have to export JPGS and place them into another file to arrange the creative properly for the mockup approval.
