Lengthen chain?

[highship]

I have put a bigger tire on one of my builds and I have a very minor rub. There is enough room in the drop outs to slide the wheel back but the chain is a touch to short. If I add to the chain with 2 links it is to long. Is there anyway to lengthen a chain by only one link?

I have bought 1/2 links at the bike shop before to make chains a little longer.

I just googled half links and thats perfect! I think that would give me just enough to slide the wheel back a hair. Thanks!
