Can I hide an iMessage group without leaving the group on iPhone?

I want to hide (that is...never see) an iMessage group without leaving it.

I don't want to just "Hide Alerts". I want to appear to be in the group but never see it in my list of messages. Is this possible without jail breaking? Any apps?

PS I am not being shady or anything like that. There is someone in the group I cannot stand but to leave the group would cause friction. I simply do not want to participate or see it.
