Articulate Storyline 3 Question - Back Button (not re-watch previous slides)

Hi everyone, 

I am currently working on a SCORM package for work using Articulate Storyline 3. It's looking good and I am getting a lot of positive feedback. Here is the resource I am working on so far: https://360.articulate.com/review/content/13a2362f-d7ce-4827-9636-2f7f8abb15a5/review 

I have a question. For every slide, I have created interactive back and forward buttons. To ensure trainees/learners (our audience) reads all slides, the forward/next button does not appear until after a certain amount of time, but they can click back/previous when ever they want. 

The issue is, if they click the back/previous button, then they will have to re-watch the whole slide from scratch. 

Is there a way to adjust the trigger of the back/previous button, so that it returns to the previous slide but at a later part of the previous slide (e.g. so that the next/forward button is immediately available and that they do not have to re-watch the entire previous slide)? 

Thanks everyone!
