Multi feature datasets for open data page

[AnnaCarnson2]

Hi, I wonder would anyone have an idea for this. We have large data sets containing multiple shp and text files that create a single data set i.e. the individual items make no sense on their own. I wanted to add these to our open data page but as a single download. I was trying to add it as a zip file to AGOL and then share the zip but when I did that the open data page picks up the individual layers and puts them out individually. I know you can't share FGDB with open data, so does anyone know of a good way I could put this up as a single dataset? Many thanks!
