Hi, hope you're doing great too!

To address your issue, it depends on the fields you've included in your copyable sections. If you'd like to prevent users from selecting the same Product Name in subsequent copies, you can use fields like Single Selector, Get Data from Other Apps, or Code Scanner. I’m assuming you can use the Single Selector block for Product Name, but if it isn’t one of these fields, you can consider using Single Selector if that’s convenient.

Here’s how you can set it up in Design App:

Add the Single Selector block as the Product Name in the copyable section and configure it with the options (if you have made submissions to your app, it is better to download the data before deleting any field).
Click on the Section.
In the right panel, go to Advanced.
Under Fields to Prevent Duplicates, select the field you want to use to ensure unique selections in each copied section (in this case it is the Single Selector block).

Here's how it will appear in the App Home:

This will help you prevent users from choosing the same Product Name across different sections. Let me know if this works for you. You can also raise a support request if you need tailored solutions.
