Exclude some woo-products from affiliate-tracking

Hey there,

I use affiliate enterprise together with woo..

1. Please, how can I exclude some products from tracking for affiliates?

2. I think I wanna purchase affiliates-permanent too, but it is possible to setup an expire date of 12 month for example? Meant is: If a customer comes over an affiliate, the affiliate should earn for every purchase of this customer for a period of 12 month (or 3 month, 6 month eg). It is possible to set this up?

Thank You!

Cheers
