If there are multiple matching scan definitions - only one is triggered when all matching should be triggered

[hlindberg]

If there are multiple matching scan definitions - only one is selected. This is bad because someone may say something that should match multiple scanning rules.
In my case matching multiple mentions of different things - say I have one scan rules for "fruits" and another for "vegetables" and I like all to be expanded irrespective of
the order they are entered by the user.

To solve this, I had to handle all possible scans in one and the same scan entry.

Would love this implemented to match all scans, as well as allowing us to toggle the behavior.
