Is there any way to tell if a track is DTS or DTS-MA using just MKVToolnix?

I'm mostly working with batch files because they're more flexible in the long run (ie they're easy to edit when they don't do exactly what I want, and easy to change back when I'm done) but as of now I have to customise them manually depending on whether the file contains DTS or DTS-MA (or Possibly DTS-HRA). I could get that info with the command line version of MediaInfo but I'd rather not complicate things with yet another program. It would be nice if I could get all necessary info directly from MKVMerge (or MKVINFO) but I haven't figured out how at at this point. MKVMerge, DTS-MA does it care?

using the normal minimal mkvinfo output:
- you can only know that it is DTS-MA/HD by guessing that everything with more than 6 channels is not normal DTS
using the verbose mkvinfo output:
- you could additionally calculate the average bitrate and decide based on the average bitrate (bitrate > 1536 -> HD/MA)

-> using MediaInfo is definitely the easier way

*sigh* Is there any chance I can get the MKVToolnix Track ID from MediaInfo? Please don't tell me I need to use both to get the full set of information, that's just... wrong!

Simply subtract 1 from the ID.

Example 1:
mkvmerge output:
Track ID 0: audio (A_VORBIS)
Track ID 1: video (V_MPEG4/ISO/AVC)

MediaInfo output:
Video ID : 2
Audio ID : 1

Example 2:
mkvmerge output:
Track ID 0: video (V_MPEG4/ISO/AVC)
Track ID 1: audio (A_VORBIS)

MediaInfo output:
Video ID : 1
Audio ID : 2

this assumes you use the current mkvtoolnix and MediaInfo versions.
(older MediaInfo versions did not respect the order of the files and older MkvToolnix versions had a different mapping)

Ps.: if you look at the output of mkvinfo, don't mix 'Track number' and 'Track ID' !
