Windows – How to add an option in the context menu in Windows Explorer to split files by 15 GB chunks

I often need to upload files to Microsoft OneDrive, whose max size per file with my account is 15 GiB.

How can I add an entry in the context menu in Windows Explorer to split files by 15 GB chunks?

Ideally I'd prefer if one could select several files and split each of them by 15 GB chunks at once. But even just splitting 1 file would be convenient.

7-zip doesn't have this function by default:

I don't want to have to manually define the split for each file:
