IS there any way to display records in table form on SR create page?

Summary:

We have a requirement where, while creating a Service Request (SR) from the Service Profile, we pass a custom variable through the SR URL to capture the selected multiple Asset IDs. The customer expects the same selected assets to be displayed on the SR creation page.

However, in our Service Centre setup, we need to modify the fragments to customize the page layout. I am trying to understand how we can display those selected assets on the SR create page, and also how to enable users to add more assets on the same page?

And how to get page level variables to fragment level?
