Adding tags & eleventyComputed to specific Global Data JSON files without subd & pagination?

[debatz]

Hello,

I am in the middle of a very data-intensive project with 11ty.

Right now my workflow is:

Intake --> _data/nameofwebsitescraped/nameofwebsitescraped.js with API call

Treatment -->

1. /src/products/websites/nameofwebsitescraped/index.njk (list of all products from said website)
2. /src/products/websites/nameofwebsitescraped/categoryofproduct1/index.njk (pagination and specially using tags to then use Collections for sorting and listing)
3. /src/products/websites/nameofwebsitescraped/categoryofproduct1/11tydata.js (special data treatment using eleventyComputed according to each website particularity, including computing a standardized weight for sorting)

Now I'm thinking while the pagination gives me a great deal, it might not be the best thing for SEO as I don't have much room to insert content and certainly not custom content per product (unless I make yet another Global Data JSON/JS and a parametric ID for each product I can leverage if that makes sense).

Is there a way to create specific 11tydata files that affect only a certain Global Data file outside of subdirectories and pagination? Hmmm
