It shall be possible to share a certain field in one tracker such that it occurs in a multi-select in another tracker.
It shall be possible to have static values in the multi-select beside the dynamically added entries.
E. g. I have a tracker called "release" which has a field "version". If I add an artifact in release I want to have the content of the "version" field automatically showing up in the multi-select in my bugtracker.
