Hi. Regarding automation, since all materials do not have a standard, they can not be automatically edited. And if the method helps in the case of one game, the other will not cope. So everything is in the manual
The fact that you can work in CorelDRAW is already good. Corel is quite a powerful tool, it can prepare files for printing. If you do not need to change the text, otherwise without a photoshop (or another bitmap editor) it will be difficult. Concerning teaching aids, read the articles on the forum. And if you have any questions, ask more specifically. And welcome to the pnp community
