In CRM terms, a sub-class of P89 Propositional Object makes sense to me.

In a 'Spatial History Ontology' I developed a few years ago (and never wrote on outside my dissertation), I developed six modeling patterns and extended DOLCE to account for them, one is Groups and Membership. 

I also studied CRM patterns closely at that time. One gap in both is what you describe, and I called it a FunctionalGroup (FGRP). In DOLCE terms it sub-classes Collective:

Endurant
- Social Object
-- Non-agentive social object
--- Collection
---- Collective
----- Functional Group

Examples I gave included 'central European farmers circa 1200 CE,‘ Bauhaus artists, U.S. Presidents, French speakers. These groups are only together incidentally or by fiat, in many cases distributed through time and not capable of agency. There are some cases that strain this conception, for example the people present in a square, who later became a (very agentive) mob.

There are many more types...an excerpt from that work:

******
Functional groups are necessary to specify and discover meaningful aggregations of persons without requiring declarations of identity. For example, set (group) membership could be a function of:
- Legal or otherwise formalized membership in a role: citizens(country); residents(place); employees(organization); members(organization); registrants(conference); etc.
- Event participation: participants (event)
- Relationships: friends-of (person)
