Guarantee target isnt repeated for 5 weeks per member

Backstory: Im the vice president of the assassin society, each week we assign our members a "target" they need to hunt down in the span of a week. I have a script that generates members targets

I need a method to make sure it doesnt repeat a target for at least 5 weeks per member. How would i go about this?

Heres the code that generates the targets:

targets = names

huntList = []
for member in names:
    unique = False
    while unique == False:
        target = choice(targets)
        if target == member:
            unique = False
        else:
            targets.remove(target)
            huntList.append([member, target])
            unique = True

for item in huntList:
    print(item[0], "is hunting", item[1])

And here is an example of the what "names" would be ['Daniel Allen','John Smith','Millie Stanford','Alex Tritton','Ashely Ward','Beth Madagen','Callum King','Charlie Brennan']

(names in the above list are random for the sake of privacy)
