Mass Assign Grades?

Hi there, I am a primary teacher in first grade. I am just starting to set up my idoceo and because I am a primary teacher, I tend to use + and - and the check mark to give grades. Is there a way to mass assign one of these icons to all students? For example, if all of my students got a + on one assignment, can I mass assign this grade to all students? I was able to do this in my last iPad gradebook program, so I am curious. Thank you!

Welcome robinlh,
Fill in a cell and then Tap and hold on it > Copy > Column
There is also the pretty fast copy/paste option explained here
