In order to find a job within ERPM with specific management set name, system and account the only way is wot query the database directly and join a bunch of tables to find the data. The Get-LSListJobs does not provide any information on the management set, system or account.
There are 2 ways to fix this problem
1) provide more data in the Get-LSListJobs output and let the programmer filter the output
2) provide a new method to allow filtering of the data
