The prevalent modus operandi within the framework of quantum resource theories has been to characterise and harness the resources within single objects, in what we can call emph{single-object} quantum resource theories. One can wonder however, whether the resources contained within multiple different types of objects, now in a emph{multi-object} quantum resource theory, can simultaneously be exploited for the benefit of an operational task. In this work, we introduce examples of such multi-object operational tasks in the form of subchannel discrimination and subchannel exclusion games, in which the player harnesses the resources contained within a state-measurement pair. We prove that for any state-measurement pair in which either of them is resourceful, there exist discrimination and exclusion games for which such a pair outperforms any possible free state-measurement pair. These results hold for arbitrary convex resources of states, and arbitrary convex resources of measurements for which classical post-processing is a free operation. Furthermore, we prove that the advantage in these multi-object operational tasks is determined, in a multiplicative manner, by the resource quantifiers of: emph{generalised robustness of resource} of both state and measurement for discrimination games and emph{weight of resource} of both state and measurement for exclusion games.
