How do I prevent duplicate actions when using macro events?

[tjensen]

Here is my scenario
I want to use a two event combination but one of the events is also used in another action

Some Group
....Action A
....Macro Event
........Channel up
........Key 1

....Action B
........Key 1

When I press Key 1 I get Action B – This is good
When I press Channel up Key 1 I get Action A but then get Action B

I would like to use these event combinations.
How do I prevent Action B from occurring when the macro event is triggered?
