Manage multiple objects in Native App

Hi All,
in my application there is a carousel like instagram where are displayed multiple objects ( like photo or event ).
I would like to navigate through each object and click over it independently from the number of object visible .
So I think to use a object repository with common properties that should allow not to return a single TestObject but an array of testObject; but I cannot find any statement that allow giving an object with input, an array of testbobject found.
As I know, Appium allow to take multiple object by search but I cannot find relative command in Katalon.
Any suggest? Thank you in advance
