Content left justified

Dear all,

it seems like most content blocks are mid-centered in Rise 360, right? Well, of course you can choose if text blocks or headings shall apper left, right or in the middle. 

But is there no possibility to combine different content all left-justified, on the whole site?? As you can see in the screenshot, Text, Text-images-Combinations an images are mid-justified. Not a pleasure for the learner, I think left-justified Content is much easier to get in Mind. But how can I change this? Any Ideas?

Thanks in forward,
Annika
