Augmented reality - LeanTouch/Lean Touch - What to do with multiple objects & how to reset position

Hello, I'm using this handy "lean touch" asset to add touch features to my augmented objects, as I have very little scripting knowledge.
I'm following this tutorial: https://www.youtube.com/watch?v=Y-HZiZoWAtM

Question 1: In my project, I have 2 image targets and two 3D models attached to them. If I apply Lean Touch (as in the video) in both 3D models, I can move, scale, and rotate the two 3D models. However, If I move/scale/rotate one 3D model, then the other 3D model does the same thing. I really would like to do that seperately for the two 3D models. Do you know what I can do?

Question 2: If my android phone recognizes an image target and augment a 3D model, I can rotate/scale/move it freely. If I remove the image target away from the phone’s view and then put in the view of the phone again, then the same transformations (for example when I make my 3D model very small with scale the first time) still apply the second time I show the image target to the phone. How can I reset the transformations to its default settings (The very begin position of the Augmented 3D Model) when my phone detect the image target for the second time?
