Create a log in an existing logset

[ismith]

It'd be great to have a command to create a log that belongs to an existing logset - or even a command that takes a log name, a logset name, and creates the logset if it doesn't already exist.

I don't see, in either the REST API or lecli, a way to do this, even if 'create log' and 'add to logset' are separated. Contrast https://api.logentries.com, which can do this with

{
  'request': 'new_log',
  'host_key': logset_key,
  'name': log_name
}
