We're starting to use JIRA Portfolio and are uncertain how to represent certain real-world situations.
In our plan, several initiatives will all require the same feature to be built. Initially I intended to represent that feature as an Epic linked to all the relevant initiatives - but that can't be done (1-1 only). My next thought was to separate that feature out into it's own initiative and add dependencies where relevant - but that can't be done either. Only epics and stories can have dependencies but it's the delivery of the entire initiative that depends on having this feature in place, not any one of its other features.
Any thoughts on how best to model this?
