forking a specific content type in Moodle


Hello all,

I have a question I could not find the answer to on this forum. 
I'm using the content type "Column" within my MOODLE 3.7 environment. 
Within this column, I'm using the content "text".

This content (text) i would like to fork, so that teachers could select the fork, and (for instance) allways have the right settings.. (such as lettertype, font size of background color).

Where can this be done within Moodle? 

Thank you!
