Mask Affiliate Links with xsitepro?

So I have created my page using xsitepro, however I cannot find how to mask my affiliate links? Right now I have them just as normal hotlinks, but want to mask them before I start promoting. Does anyone know how specifically in xsiterpro? Or do I have to add a script?

Can use the redirects feature, is just a meta refresh but can make the url whatever you want
