Currently, when I work with a cloud project in Trados Studio, I see that "Release Task" button in the banner is greyed out when multiple files are selected. The button is avaiable for single files only. I work on cloud projects containing dozens and hundreds of files daily as a PM and I often need to do some manual preparation locally after the cloud project is created and downloaded to Trados Studio before returning them back to the cloud and re-assigning to the translators. 

I suggest if RWS could make the button available even when multiple files are selected. I clearly remembered that the "Complete Task" button used to be greyed out when multiple files were selected in earlier Trados versions. Now, the "Complete Task" button works for multiple files, even hundreds of files. Hopefully RWS could do the same for the "Release Task" button.

I guess some may argue that I can create a return package to do the same. 

The problem with a return package is that, I cannot tell exactly when all the files in the return package has been successfully implemented into the cloud project, or in other words, has successfully overwriten the original files in the project in the cloud. When a return package gets uploaded, I see a message at the top-right corner saying something like "your package has been successfully uploaded, but it may take some extra time for it to be processed." And I never get to know when they are successfully processed. Nor is there a "Last Modification" column in the Files view to indicate the last modification date/time of each file. I usually wait a couple of hours or until the next day to reassign the project.
