I was so much pleased with answers to my questions from this forum.
The forum is one of the "pros" of choosing C2.
Kyatric and codah, thank you for your carefully written answers.
Now back to the topic:
Not every language has dynamic names. Not a big problem.
On trade-off side, c2-IDE can refactor object-names by one click.
I asked for "dynamc-names" only because of, in my case, c2 half-fails to pic by UID.
This is either my fault or c2-bug described in example on the bottom of the picture in event "65".
Yes, i must look at "nickname" plugin.
I no longer need the answer because no time to do my own research and "homework on c2".
