When creating a filter in BT 360, you cannot filter on the same item more than once.  Once you select it, you cannot filter on the same item with a different parameter.  For example, in the Advanced Event Viewer, you cannot filter a match on ANY of Type equal to Error OR Type equal to Warning.  And, you can't even get around this by saying not equal to Information. This is something that you can do if you are in the Event viewer, but not in BT 360. 
This seems to carry over to other areas as well.  For data monitoring, you cannot filter on two Service Names for example.  Also in ESB Exception Data, for example, you cannot filter on two fault codes.

I would like to see BizTalk 360 allow you to select the same item for filtering more than once, as you may need to use the ANY logic to find things that have two values for the same item.
