Offload to s3

Hi author

I am absolutely satisfied with your lite version plugin and would like to go to your PLATINUM plan before i can figure out the below question:

Background:
I use ultimate member as my membership plugin, and it stores user’s uploaded images such as avatars, wall post image, etc in this folder – public_html/wp-content/uploads/ultimatemember/. As the images in this folders would not be shown in the media library dashboard, i would not able to use your premium offload tools to offload the images manually myself.

1. I would like to know a solution as to how i can offload the images in that folder to s3?
2. And at the same time, i can also offload the images to s3 uploaded from the default wordpress post system.

Thanks
Patrick
