Layer focus between slides

If I am working on a specific layer (say layer 2) and have “clicked” on it so it has [focus] and want to compare in the following slide, I’ll move to the next slide by clicking on the {next slide button}.  When clicking back to the previous slide I find the [focus] has moved from the “target layer (2)” to the layer at the top of the list, layer 1.  This is a frustration when working on 36 layers!!  I would like to have the ability to move back without having to scroll down back to the layer I want to compare.  i.e. the previous slide and keep [focus] on my working layer. Can this be done?
