breadcrumbs to track always products home category

-- HikaShop version -- : latest
-- Joomla version -- : latest
-- Browser(s) name and version -- : chrome

hello,

first question: with canonical url ON (from hikashop settings), when i try to reach a category or a product it sends me mostly to root of my page, so it cant find the path. How to make it work?


second question: the thing i want to achieve is when i have a product attached to one or more categories( i will call those categories its HomeCategories).

i want always display the product with breadcrumbs tracking thru its HomeCategory.


Example:
structure of my page:
-root
--informations
--blog
--eshop
---category1
----category1.1
----category1.2
---category2


i have my Product1 attached to category: category1.1

Situation: now im browsing in category1 and click on a Product1.
Current result: on product page breadcrumbs shows path: root>eshop>category1>Product1
But i want it to show a path thru its HomeCategory: root>eshop>category1>category1.1>Product1

.......or how to set Canonical URL of a product to its HomeCategory easy. Only way i know to make it, is to create a new product, save it, find it in frontend, copy/paste url to "Canonical URL" field of product.
Is there a way to set this wholesale for all products or som button on product backend page, to fill the "Canonical URL" field properly.

i think this is the way it should be by default, but im newbie on hikashop

thanks in advance
