An issue with copying?

MIT App Inventor Help

I needed to copy sentences and buttons and screens but I couldn't,I hope you make everything can be copied and thing from outside the application can be pasted and things can be copied more than one time by choosing the number of times

Is this when developing your app, or when your app is running?

Provide examples, screenshots, video, blocks etc.

Why? Purpose? Example(s)...

If you want to create 50 or 100 bottons for example use DynamicComponents or CompCreator.
