Build with Parameters view extension

Hello everyone,

I would like to extend Build with Parameters view for more complex interactions with user. As example I would like to add tabs and JSON generator. I know there is an Extended choice parameter plugin which has JSON Editor implemented already. But I would like to not to use this plugin. Is there a way how to extend Build With Parameters view? I would like to avoid creating some plugin which will behaves as another parameter if possible. Do you maybe know if there is already some plugin extending the view or do you know how to extend the BuildWithParameters view?

Thank you in advance for any help.
