Picky customers and the case of the issue in two releases

[Juan Carlos Gil Montoro]

Let me tell you my use case.
We have a software base being enhanced and fixed by several teams, each with its own JIRA project and backlog. The software is used by a series of customers that may ‘cherry-pick’ what bugs/enhancements (issues) they are interested in for their own releases. This is intrinsic to the nature of the software and can't be avoided.
So assume we have two teams, Team 1 and Team 2, each with three issues in their respective backlogs (1 to 3 for Team 1 and 4 to 6 for Team B). Now assume we have two customers, A and B, and let’s say customer A is interested in issues 1, 3, 5 and 6 while customer B is dying for issues 1, 2, 4 and 5. Notice how both customers want issues 1 and 5, while other issues are requested by one customer only.
(Please see the attached image for a sketch of this example)

How could we configure Portfolio so that there is a “Release for customer A” including issues 1, 3, 5 and 6 and another “Release for customer B” spanning issues 1, 2, 4 and 5, provided we can’t assign an issue to two different releases?
Ideas welcome! ^_^

I found the answer myself: the sentence "provided we can’t assign an issue to two different releases" is actually FALSE, Portfolio and JIRA allows to do that.

So so far so good.
