Force KFX format in eInk Kindle Oasis 2017

Hallo,

I bought a book on Amazon, which was featuring the "Enhanced Typesetting" option. After getting it on the Oasis 2017, the 9 thumbnail Pageflip was not available. On the kindle for PC the downloaded folder structure is similar to KFX-format detailed on some website. On Android the downloaded files were multiple KFX files.

Is there a possible get one file-KFX-version on Oasis 2017? I tried converting the AZW3 using calibres KFX output plugin but the tables get messed up in the process.
Is there is a way to convert the downloaded content from other platforms to an Oasis 2017 compatible KFX file?

Thanks
