Katalon Studio taking long time to add test cases (~500) in test suite

Hi,

I am adding ~500 test cases to my regression suite and it is hanging.

I had to pick 100 test cases at a time and add them in the suite, which is time consuming and I am afraid when my regression test cases reach ~ 2000; the situation might be worse.

I am using Katalon version 5.4.1.

Can you please check and see if the problem is happening at your end too?

How much time is expected to add ~500 test cases in a suite?
