I am creating a WMS service made up of linestrings pulled from a POSTGIS database

I want to label the start of each line with a sequence number. At present I can label the centre of each with:-

```
 PROCESSING 'LABEL_NO_CLIP=1'  (to prevent repetition across tiles)
 ....
 LABEL
      COLOR 132 31 31
      TYPE TRUETYPE
      FONT "arialbd"
      SIZE 12
      POSITION AUTO
 END

```

This places the label in the middle of the line string. Any idea how to place it at the start?

Note that GEOMTRANSFORM "start" does not work with labels
