Copying lessons across multiple classes

Is there a way in the planner to easily push out lessons written for one class to other classes on same and/or different days? Or to link the diaries of multiple classes? I feel like I'm missing something by the struggle to copy and paste.

Open a class' diary (either day,week,month) > Tools > Copy diary annotations
This will let you copy a range of dates into another class.

Or for a single day: from the planner, tap on Options > Copy and select the target class and date. There is no need to copy/paste
