Metalar ve filtreler

[Tnmv23]

hello everyone, I've been researching meta fields for a long time and I can't create the meta structure I want because I'm in a constant restriction I want to create a structure that allows me to control everything from 1 place (filters, specifications, comparisons), etc. I'm trying to shorten the time while logging in to the product as much as possible, such as checking everything (filters, specifications, comparisons), etc. ;
i can only use one of the metafields under meta object as a filter, which is the biggest problem for me because I not only have a feature to filter, I have many features, my only goal, of course, as I said, is to provide input of all data from somewhere and make product input as soon as possible
