Is there a way to post an asset to a channel without it appearing on the Activity Feed? 
 

We use the platform as our intranet and host commonly used documents/forms/etc. When one new asset is added to the system, we want it to show on the activity feed so people know it is there. However, when a new Channel is created with multiple new Assets, it takes over the Activity Feed. 
 

I have tried variations of keeping the Channel “hidden” by only giving a Group access to it. Then making it public once it is all uploaded. But I haven’t figured out the magic steps if there are any.
