Subject: extract targets as a set from whole area

Hi Everyone:
I have a new problem of setting tartgets as a set.
At first I set target , which is a instance variable of agents in my model( the agent will walk towards the target), like this:
touristNeighbours := (self perception:10) select: [:cell | cell theme = #Attraction].
target := Cormas selectRandomlyFrom:touristNeighbours.
in this way the Target is related with the agent's location.
Since the Targets set of all agents is the same (diferent agnets visit the targets in different order). What I am trying to do is to extract targets set as a collection from the whole study area(all the cells with the attribute of #Attraction),the targets set will not related with the agent's location. I don't know whether it is possible to set the Targets set under Agent protocol or should it be set under the spatialEntitySet protocol? Should it be a Composit Spatial Entity->Fragmented spatial Entity?
Great thanks!
