Magento 2 - Modify Amasty Product Parts Finder Extension

I have some csv files that have around 15000 rows of data in each. I am looking to import some CSVs with all the data already in them. It has about 10 columns. I was thinking about using the Amasty Product Parts Finder Extension to do this but it will not work out of the box and needs a slight modification. So if someone selected column 1 data it filters to column 2. Column 2 filters to 3 etc all the way down to column 8. I would like then for the website to do an advanced search on an existing attribute for the data contained in columns 9 or 10. I have about 4 different spreadsheets of data and I would like to place a different dropdown search on CMS pages. I think the Amasty Product Parts Finder Extension searches for the exact SKU rather than an attribute of the product? (correct me if I am wrong?) In my case I am trying to do an OR advanced search for the contents of Columns 9 & 10. That's the modification.
