I have a requirement to enable adding tests directly in test sets. Presently, when we try to add a test instance there, it shows just 2 columns. Test ID and Title. There is no way I can add more columns and resize the window.

That's required when we want to create different test sets as per execution type, test level or as per area/application field(custom fields).

Only way to do that now is create different filters as per the need in test library, get the tests and add them to the instances.
Since in my one project, I have 5-6 applications, then different areas, different execution type, test type, it's becoming cumbersome to keep the filters up to date. Moreover, its all manual efforts as there is a limit of just 50 auto filters.

I had to spent many hours to have proper filters. And now if I have to add any custom field, I have to redefine my filters in test library.

It would be really beneficial for my project to allow seeing different fields of tests while adding them to test sets in the respective area.

Can you please look into it.
Thank you in advance
