avoid repetition of task names in invoice template

Hello everyone,

I have a question on invoice templates and on the way to adapt them. I currently have an invoice template that, for each item row, reports:

- task name,

- quantity of CAT-match,

- price per 1 match,

- total price for all matches in that line.

I would like the template to have the task name mentioned just once, the first time it appears (not repeated in each row) like in the image below:

Have you got perhaps any suggestion on how to achieve this?

Kind regards
