Hi Edward,
Thank you so much for sharing!
I really love your idea, I think it would be a very beneficial option to upload files directly from the cloud storage. We’ll try to think about this possibility in our future updates 
By the way, in our latest update we increased the max size from 25 MB to 100 MB, you can find the details in this post (Maximum file upload size increased to 100 MB) .
A huge thank you for helping us!
