(ERP) Software Simulation Project. Maximum number of slides

I plan to create a software simulation project. It is an Enterprise Resource Planning (ERP) type of software. Example is Customer Relationship Management software.  I was wondering what is the best strategy to create this entire project because this will require hundreds to thousands of slides. As you know that each click in the software is one slide already. 

My plan is to:

1) create a MENU slide as the main .cptx project. In the menu slide, it contains list of lessons which the end user will click and will direct them to the simulation topic itself.

          Menu (Main .cptx project)

                     Lesson 1 - Create Customer Profile

                     Lesson 2 - Create Supplier Profile

                    Lesson 3:  xxxxxxxxx .........

2) Create separate .cptx for each lessons.

3) Copy the slides from all the lessons .cptx projects and then paste the slides to the Main menu.cptx project.  The main menu .cptx project with all the lessons simulations will be the one to be deployed.

I am not sure if this is a good idea. As mentioned earlier, it is a ERP software simulation. if I develop this in one cptx project, this will have thousands of slides. Will there be an issue in the elearning performance, if one cptx project will have thousands of sildes?

I plan to divide the simulation project into 2 modules as well.

Would like to ask some inputs from those who develop software simulation project.

Thank you
