Hi, Vikas.
I am reviving this forum post to tell you that since Service Studio version 11.10.16 editing your data is at least 10x faster! You don't need to jump into SQL or create a form/full back-office anymore. You can now quickly add, change and delete your entities data directly in Service Studio under environments with a "non-production" purpose.

Let us know what you think! :-)
Have a nice weekend,
Ângela
