This is what I mean.
On the widgets page, there is a long list of sidebars that I can open and add widgets to. There is a single one for all woocommerce pages.
My wonderful theme allows me to create new sidebars, but the woocommerce doesn't have any links to include single woocommerce product pages in these.
Does that make any sense in regard to your reply - which I have no clue about.
