Assigning an interactive activity by excluding a specific participant

Question

Hi,
I'm trying to implement an approval process using ALBPM 6.0, and have a problem couldn't solve effectively.
There is an interactive activity (let's call it actA) assigned to roleA, a second activity(actB) assigned to roleB. actB executed after actA and an unconditional transition placed between them. Both roleA and RoleB have some common participants. The problem is, both activities shouldn't be assigned to the same participant. How can I guarantee that a participant who has assigned to roleA and roleB does not see actB in his inbox if he executed actA?
Do you have any suggestions or a solution?
Thanks.

Here's the logic that does a "round robin" assignment, but excludes a specific participant.
role as Role = Role.find(name : "Employee")
parts as Participant[] = role.participants
indexStored as String = retrievePropertyFor(Fuego.Server,
                                    application : "RoundRobin",
                                    name : "LastParticipantIndex")
lastIndex as Int
finished as Bool = false
excludedParticipant as String = creation.participant.name
if indexStored = null or indexStored.empty then
    lastIndex = -1
    // we will start from zero
else
    lastIndex = Int(indexStored)
end
while not finished do
    lastIndex = lastIndex + 1
    if lastIndex >= length(parts) then
        lastIndex = 0
    end
    if parts[lastIndex].name != excludedParticipant then
        finished = true
        participant.next = parts[lastIndex]
        logMessage "This instance is assigned to " + participant.name +
            ", lastIndex = " + lastIndex + ", indexStored = " + indexStored
    end
end
storePropertyFor Fuego.Server
    using application = "RoundRobin",
          name = "LastParticipantIndex",
          value = String(lastIndex)Hope this helps,
