DynamicProxy to the project hierarchy

I have a problem with generated objects by scripts. All I want is just start preview mode to start a script --> generate some objects by the script --> copy them during preview mode --> end previev mode ---finally--->paste to my project hierarchy , but there are DynamicProxy objects instead which u cant save etc. I know that I did it that way in Roblox Studio and worked perfectly. Is there any way to have that Dynamic Proxy objects directly in my project ? I can see opportunity to print objects info and paste it somehow to the "Templates" directory in my local disk but I hope there is any easier method and less time consuming?
