Can I have two or more context for an action or project? for example one as member of the team an another one as geographical? I didn’t find it
No. Currently OF only supports a single context on a task. It sounds like this may eventually change, but keep in mind it’s been 8 years since the request was originally made so it may still be a (long?) while.
You might consider using hierarchical contexts; they can often do something similar you might want.
