Is it possible to update the Groovy's version? Do while loop


I need to do something and, to implement it in a clear way, I thought about the do while loop. I tried it but it is not recognized in test cases nor groovy files.

So I wondered, searched and saw that is possible to use it from the version 3.0, but I also found this link:

Would it be possible to update Groovy manually, that you can add it in new releases of Katalon, or even make it specifically updatable from the IDE?
