When learners request reasonable accommodations for assessments / testing for reasons related to accessibility / learning diversity, how are you going about making this change for the individual learner?

For example, our assessments usually have a one hour time limit, but a learner has requested an extended time limit as they are dyslexic. In the past (and with a previous LMS) we´d create a different version of the course / exam with an extended time limit for the learner, but I´m trying to avoid this in TI if at all possible. However, I don´t see any way to adjust this at the user-level. 

How are you handling similar requests?
