Does anyone else have trouble taking a feature from one template to another

I love that Snapchat Lens Studio offers templates to easily get up and running, but over the past 2 months of development whenever I want to have more than one feature in a Lens, I find it extremely difficult to move assets/scripts/etc to another project. 

And in all the documentation, it starts off from the template, so if you're not in that template, but trying to build that feature, it's very difficult. 

To give an example. I started with a sunglasses template but wanted to also have a segmentation feature. 

So I downloaded the segmentation template to get the assets, but when I did I didn't find the assets in my finder. When I opened the project in Lens Studio, I then saw the Segmentation Textures. But when I tried to export the portrait background texture to my original sunglasses project, it came out as a .txt file and I was unable to use it and thus I had no way to use segmentation without that texture. 

Does anyone have similar issues or have an answer to my dilemma?

Thanks!
