Is the --no-combine-classes switch broken ?

Hi,

I have a very simple json file.

When using the online tool (app.quicktype.io), I can use the "Merge Similar Classes" toggle button to customise my output (json to code). However, when trying to do the same from the command line, the "--no-combine-classes" switch has no effect and quicktype always leads to merging.

quicktype -t Trade c:\temp\Trade.json --lang cs --array-type list --features complete --no-combine-classes -o c:\temp\cs\Trade.cs

As an example, with the json snippet below, online, I can toggle between merging the 'Rate' and 'Amount' generated classes.

Via the 'quicktype' command line, these two classes are always merged into a 'Rate' class.
Am I using the correct switch (--no-combine-classes) and in the correct manner?

Many thanks,
Best.
