In Columns you're not allowed to upload single tasks - which means you need to make this content type from scratch. Any plans to enable upload of h5p-content to steps/sections in Columns?
1) Create a Column resource
2) Click "add content" and upload a previously made "drag and drop" for this section in this new resource from your desktop
3) Click add and create a "fill in" on the spot
4) Click add and upload a previously made course presentation....
This would make Column a great tool for remix and sharing.
