HI graphiclux ,
Thank you very much for your post.
We have already spoken about similar feature for ATUM inside the team, however, as of now it is has not been developed. Not sure if we find time doing this next year, best option would be to setup one WC site that pulls in all the data from everywhere and have ATUM view the information. ATUM should be able to see anything that WC can see.
Hope this helps.
