Is it possible to add »individual content« to cms-pages

I have a cms with data on about 40 different projects. I created a project template and added all the infos. Now I want to add a slider with project-images. Problem: some projects do have 4, some 13 images. And the images must be formatted different (landscape/portrait/cubic/with or without outline etc.).

Is there any possibility to access the individual project-pages and add a customized slider that is not managed by the cms to each of them?
Or do I have to build a new page for every of the 40 projects?

Thanks in advance for any help.
