Need a simple way to to add custom labels to products based on title

[Kyle_McClung]

I'm looking for a free way to add custom label fields to my products based on keywords in their titles so I can segregate them easier in Google Shopping campaigns. Basicly a free feed management tool or a way to do it in Shopify. Does anyone know of any way to do this?
