Adding keynotes to multiple objects


I am a new dynamo user.

Is there a way where we can add keynotes to mutiple objects at the same time like “tag all”.

Our projects require adding keynotes to many elements. So far, we have been individually selecting the object to add key note. Our objective is to automate the project to add keynotes for all applicable objects.

If you have any solution to do this or learn this ,please share.

Thanks in advance.
