How do I plan to create filters so that I can reuse them again and again?

Hi Aniruddha, Thanks for reaching out. The best way to do that in your case is to create a 'Build' custom field of the type list and link it to the Test Sets & Runs entity. Then, after adding all your builds as values to your 'Build' field, you can create permutations of your original test set and change the 'Build' field's value for every new build you have. In order to arrange your Test Sets & Runs view in builds, you can then create a filters hierarchy for your different builds. The parent filter criteria can be - 'Build' is 'Not Empty'. Then, the child filters' criteria can be 'Build' is "each one of your 'Build' field values". In PractiTest, the Test Library is the repository of your test cases, and the Test Sets & Runs module is where the test execution actually happens. Therefore, when you want to organize your execution based on time-related items (such as builds), the best place to do so is the Test Sets & Runs module. I really hope that helps and that I have provided all the needed information you were looking for.
