How to correctly implement the dynamic creation of a scrollable set of composite elements?

Question

htaccess

There is a set of objects of the same type that interact with each other during the execution of the program.
But before starting execution, you need to set their basic parameters.
The number of such objects is also set by the user and can reach 50 pieces.
Therefore, it would be more convenient to be able to flip through the "setting pages" of each specific object.
One of the parameters is also a series of similar value sets with a variable amount.
Objects are created after setting all the parameters.
An approximate scheme is as follows: set the number of objects -> display the main window with the settings area -> set up objects -> create objects according to the specified parameters and start processing
How would it be more correct(to make it easier to work with later) to implement?
Or what alternative approach would you use to solve this problem?
UPD : clarified one of the parameters
