Assignment 2.3 - Comment Inline?

Hello everyone!  I am getting our new 2.3 Moodle site ready for introduction to a large group of teachers used to 1.9.  Everything looks fine so far, but I'm having a problem with Online Text Assignments.

Our teachers like to comment inline, and yet I can't find the setting on an Online Text Assignment that allows me to set my comments inline.  In 1.9 there was an obvious setting....but is commenting inline still available in the 2.3 version of Assignments?

I have a feeling this is something simple I'm glossing over, but I would greatly appreciate anyone's help with finding this crucial function.

Thanks!
