We too wish we had a system name, but try as we might we can't find one that suits us all.
As it is we answer to the body's name, but as far as we know there is no-one here who actually claims that name as their own. Plus, we *hate* the body's name. Because we are not that person! It is all so frustrating.
We often slip up and ue 'we' in public. It seems to go by unnoticed most of the time. Or people assume we are talking about us and someone else. I don't worry about it too much.
