I am creating an app and noticed that the accelerator doesn't allow the creation of individual actions. For example, I have this Entity Diagram:

I used the entity (MyList) to fill the List in the tab (My List):

After I added that List, I dragged and dropped the next entity (Product) to my other List:

That is related to this tab (Products):

That in my opinion, it has to display everything that the table (Products) contains. However, what is doing it's referring to the GetMyLists aggregate instead of creating a new one.

What could be a solution?

Verify if the value already exists but if the user tries to add it more than once, it must create the other aggregate function by default.
