Unable to edit product specifications layout and conten

Ok, I found template editing area of a single product. All spec icons can be edited and names changed. The question remains how to populate relevant textual specs in to each spec field? Where this retrieved from? If manual, it is impossible as only Color and Brand can be auto added. I need to add text in to specs.

Thanks for the answer.

BUT.

the specifications for each product a different. I know I can create multiple layouts for each product type. The content block that contains specification names, can not be edited to add or remove new specification items. Also when layout applied to a product each specification sub block shows same attribute. Can I have an explanation how I can get Attributes with their terms be unique for each specification elementor block? I think the product doesnt suite me at all. example of my terms for new attributes are here: https://securitycamerasonline.com.au/collections/hikvision-security-systems/products/hikvision-hilook-8-channel-cctv-kit-with-6mp-turret-security-cameras

I need to show clients specs very clearly

Also, what is the best way to create repetitive product types. do you have bulk editor?

There is misunderstand.

I created product attributes and terms, selected relevant terms for each attribute for a simple product.

The specification sidebar in product view shows same attributes for each specification field. this is stupid and I dont want that.

I want icon, specification name associated with on attributed in this specification sidebar. what a nonsense. dont email me vids. explain why I cant manage your specification the way I need it. I bought this theme when I liked the specification sidebar view. but it is not usable.

I already worked out that I need to exclude attributes using data source. The question now is how not to populated all attributes by default. What it does it pushes all attributes into the sidebar table. I want to have non pushed, so I select which is needed. I now have to exclude and exclude to get right info left. Can I make default dont populate data sources in first instance?
