Kodi 18.1, pvr.hts addon 4.4.16, Tvheadend 4.2.8-23~g74cdf3f16

I have the following settings in Tvheadend for recording:

Format string: $c/$t$n.$x
Make subdirectories per day: unchecked
Make subdirectories per channel: checked 
Make subdirectories per title: unchecked

So as to create directories and files as follows:

/Data/Recordings/BBC ONE/Casualty.mkv
/Data/Recordings/BBC ONE/Casualty-1.mkv
/Data/Recordings/Channel 4/New: Joe Lycett's Got Your Back.mkv
/Data/Recordings/Channel 4/New: Joe Lycett's Got Your Back-1.mkv

..etc.

When setting a recurring timer in Kodi, however, the pvr.hts addon insists on populating an edit box with the name of the program, thereby making a subdirectory per title, which is not what I require.
Should the settings in Tvheadend take priority, or those in the pvr.hts addon?

You could just leave the directory edit field in the Kodi timer settings dialog empty.

Unfortunately, there is no way for the addon to access the respective tvh settings.
