Dynamic Tab Group or Horizontal RG?

I am creating the framework for an itinerary tool.

When the user sets up the itinerary the tool collects how many days long the trip is in a numeric range.

I want to be able to display the numeric range in a tab or horizontal RG format so I can add itinerary items and reference the specific day.

Can I use the tab group tool? Can’t figure out how to make dynamic tabs.
