When using GreenHopper, it can be difficult when filtering by assignee since our assignee list is so large. Is it at all possible to filter the GreenHopper Planning Board by JIRA group, rather than having to do it one assignee at a time?
No, this is not possible. However you could add some project contexts with a filter behind them which explicitly filter on certain asignees. So you could have a context for all the UI people, for example.
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
