Would like to move from yoast, but 1 problem.

Hello, really like the way this plugin works, but there is one thing i cant find that i depend on in yoast. I have a website ( woocommerce ) that has thousands of individual items.

In yoast i rewrite the titles, & use the description as the title

so i would do this for example

title : Website name | %tax_pa_brand% %tax_product_cat%
product description : same format as above ( but size,colour, etc )

I can find the product title to do this but, I cant seem to find an option for the product description?

Any help would be great.

All the best

Paul
