How do I bundle together my files into a single listing?

I would like to sell my clipart on Adobe Stock and wanted to make a test, by uploading a .ZIP folder with 4 identical files, in different formats - AI/EPS, SVG, PNG and JPG

But I get the following error:  Couldn't be uploaded because it is not a valid file type. Valid vector formats are AI, EPS and SVG. Vector zip files are no longer supported.

So according to the error message, you can no longer upload your files in a .ZIP file?

I can upload each file separatly, but how do I then bundle them together, to create a single listing (with AI/EPS, SVG, PNG and JPG), instead of individually listings, each one with a single file format?
