I guess we need a better idea of what you're trying to accomplish. If
it's just reconfiguring the virtual machine with some differences for a
specific userid, then it's not too uncommon to have a standard PROFILE
EXEC that tests for a <userid> EXEC and runs it if it exists. Example
code snippet:

'ESTATE' userid() 'EXEC A'

if rc ^= 28 then do
  'EXEC' userid()
  end

Your specialized startup then goes into <userid> EXEC.
