Ability to remove/denote certain elements in dimensions used in Attribution IQ attribution

Attribution IQ is all great in Adobe Analytics, but when used it in f.ex. Marketing Channels, it attributes some conversion to Session Refresh, which is unnecessary. Would be great if there was a way to be able to remove the Session Refresh from attribution and share the credit to all the other channels. Or do some more advanced rules like if direct channel is the last touch it's value is half.
