To display RESERVED PHYSICAL qty on Item Requirements Line

Hi,

I would like to know whether it is possible to add a new field at the Item Requirements Line level having a  Display method to show the 'RESERVED PHYSICAL' quantity for each item.

If yes, then is it possible that I can use any of the existing method?

 or

Do I need to write a new method.I am new to AX coding, so in case I need to write a new method, can you please give a few tips to get started.

Regards
