Adding user information to 'Try Mode' projects

Hi Team

I'm building some procedure demonstrations using Storyline 2's 'Try Mode' for a new system our business is implementing. At certain points in the 'Try Mode' demonstration, I need to point out the results of the action being demonstrated and to do that I've been using layers to make information appear in a 'pop-up', with those layers then having buttons and triggers to dismiss them or to progress to another layer with further information. I've attached an example, it's only seven slides long but you'll see the informational layers I've created in slides 1, 4 and 7 and the triggers to make each one appear and disappear.

I'm happy with the overall look & feel for the learner, but the process of building these layers into the many hundred of these demonstrations I need to make is quite cumbersome and I'm wondering if I'm doing it in an optimal way. I've saved example layers in a separate project, and I simply copy&paste them into any new project that needs them. I was hoping there might be some way to do the same using templates or slide masters but so far I've just been running into walls - for example, if I add the layers to a slide master the layers do not appear.

Just hoping some Storyline gurus might have some ideas about how to optimise the process of adding these informational layers and the required triggers on the base layer. 

Thanks!
