Copy Text with pagebuilder structure

We use a tool to clone posts (Function in Lifter LMS). After cloning posts content of the cloned post is the full pagebuilder HTML content as a text. As soon as we turn on page Builder the Text is automatically converted in a single row. In this situation it would be nicer to copy the code as it is to the pagebuilder window not loosing the structure. Can this be done by some workaround or maybe extra button?
