Can you turn off the need to click "Post" with every comment in Acrobat DC?

There are many annoying features of Acrobat DC as compared to the prior versions of Acrobat. However, one of the most annoying and time consuming is the need to click "Post" at the end of each comment that you're writing.  Is there a way to turn this off  on a default basis and have comments saved automatically?  

If not, are there keyboard shortcuts that can be used to be able to select the Post button and/or close the comment box without having to manually click on the Post box and the X in the upper right to close the comment.

Is this "feature" also present in the latest desktop version of Adobe? If not, is it possible to switch from Acrobat DC to the desktop version?
