How to add a custom field under Test Run screen from test Lab?

Hi,

I have created one custom field called "Prerequisite" under the Test Lab tab.

(attached screen shot for reference)



Now if I want to use this same custom field with information on the Test Set tab as well as the Test Run screen. I mean the user should be able to see the Prerequisite while executing the test case..what should I do?



Kindly let me know if I need to add more details.

Please do reply.



Thanks,

Parag
