Display ticket and extra service separately

Hi , I sell course on my website and also provide accomodation and charge separately for it.

I want to display Ticket and Extra service separately on invoice.

Check this screen shot : https://snipboard.io/cikwP4.jpg

I tried to drawed the template on paper to give you a better understand which you can see here https://snipboard.io/ZG4l0u.jpg

Kindly tell me how i can achieve this.
