Refinement of the section Automatic markups for goods

Good afternoon, please calculate how long it will take to refine the section Automatic margins for goods, so that when you click on the top category, all the rules of the subcategories are displayed. https://owwa.crm-onebox.com/admin/shop/marginrule/?categoryid=5076 If in our case, click on "Furniture fittings", then the rules that are assigned only to this category are displayed, and we need to see all the rules that are included in the subcategories of the main category. That is, you need a checkbox to display the rules of subcategories. After activating it, in the table with the rules, you need to add the "Category" field so that everything does not mix into one. This need arose due to the inconvenience of use, for example, we choose one supplier to change the rules, and we have to open all the categories in turn, and there are more than 150 of them.
