Duel Automation Hosts

Hi SpiraTeam support,

Could you please explain the purpose and/or logic of having one automation host attached to a test set, and one attached to a test case? As it currently stands, automation hosts can be added via the administration > Integration > Test Automation section and can also be added via Testing tab > Automation hosts. That functionality has caused confusion over the past week and we would like a clear justification regarding the intents and purposes of having duel automation hosts implemented in SpiraTeam.

Regards, 

Michael
