How can i groupby and sort a report from a bots

[HennieJanssen]

I made an APP for inspecting kitchen, toilet and bathrooms.
I made a report with the template click to sent e-mail.
See template below.
I use a slice to select certain records, but now I want the records to be grouped and sorted.
Cannot find the right start extension.
