The best way to adjust number variable in every slide
I would like to assign a number variable to each slide. Fox example, slide 1.1 (variable=1), slide 1.2 (variable=2), slide 1.3(variable=3).
I use trigger "adjust variable" to handle this case. But I need to do this many times if the course contains many slides. I also afraid that there will be some mistakes if do this manually, because the number should be use one time in the project, can't repeat use.
May I ask if there any smart way in this case? Thanks a lot!
