Subject: Can instance variable be a sortedcollection?

Hi!
I want to let my agents to visit several targets. I want to set a instance variable of agent to make a record of whether a agent has been to the targes.
For example there are 5 targets(T1,T2,...T5) for each agent to go. Then the instance variable named 'Record' should be a sortedcollection(R1,R2,...R5), the initial value of R are all 0, then if the agent has been to target T1, then R1=1, if he has been to target T2, then R2=1, In this way the agent can have a memory and not to go to a target more than one time.( Target in my model is a kind of attribute of spatial entity-Cell, I don't want to change it's target attribute)
Can instance variable be a sortedcollection? if it is possible, how can I connected sortedcollection T(T1,T2,...Tn) with sortedcollection R(R1,R2,...Rn)?
It would be very appriciated if anyone can help me. Great thanks!!
Forgive me for lacking knowledge of smalltalk!
