To the presentation, I want to add a file with a speech plan to each of the slides. To do this, I can use the independent writing of each of the texts, which in practice is not a good approach, because it requires monitoring the relevance of the information in each of the documents. Another solution is to write one file with both slides and the text to them, and then, using two different preambles, implement the creation of both files. If there are no problems with the presentation, then I have difficulties with the document. How can I insert a presentation slide in the form of an image into a document if this slide is only in the form of the source text?
Perhaps my task can be solved in a different way, simpler. If so, please share your knowledge.
