Voting Rewards Problem

[TheKM6000]

So, is it possible to not spend Shop Voucher and leave it to use next month? i mean like in this month if someone is at 7 th place and gets 10$ voucher can he leave it to next month if in this next month he wins another 10$ will he have 20$ shop voucher?
PS sorry for my english im not english

I don't think vote rewards stack, but you can ask an owner if you need to.
