Of course there is. It is named Docker for Windows. 
The multiple chapters are optional. You can also just use your three taf files with one chapter per taf. To achieve this, you can just cut the header of each taf file (the first 4096 bits) or you can just download the taf from your teddycloud library and use the url parameter ogg=true (like the integrated player does).
So in my case, I can simply open this url iin the browser and download the resulting audio file which is an opus file without tonie header:
http://192.168.178.11/content/tilt2024.taf?ogg=true&special=library
So you could just download your three tafs this way in order to get 3 opus files and then you can encode them into one taf file with the docker container on your Windows PC.
