Multi Layers with las files

Hello to everyone!
I need your help and your knowledge please.
I have 3 different dates of an area (point clouds, las files) and I want somehow to show the (time) difference between them. I tried annotations, I added the date and some information of each model but I am not so satisfied with this.
Do you know another way to show this difference? for example to click on the first model and the second model to appear and then click on the second model and the third model to appear. I know that I can do it with mesh or objects but it does not work with las files. (maybe I am missing something)

Any suggestions will be more than welcome.
