Since this is a anonymous platform, not sure if its 20, 200 or 2000 ..
lets try replies ... do this ONCE.
if you are current employee say C followed by the next number from the previous reply .. so C1, C2, C3, C4 ... etc
If you are an ex employee say E followed by the next number from the previous reply ... so E1, E2, E3, E4 ... etc
