How to pull in request reference number in a task report?

Hi everyone - I’m building a task report for my team. Most of the fields I am referencing are related to the project and task however there are a few fields I need to reference from the converted request. I haven’t been able to figure out how to pull in the converted request reference number. The best I can do is the request name. I tried to see if I could pull it in by tweaking text mode but I’m still learning and don’t really know what I’m doing.  Any assitance or guidance is appreciated.
