Find out what parts in LDD convert tot LDraw

[Jaco van der Molen]

OK, so last night I couldn't figure things out (working too late).
Now a fresh start!
I downloaded the ldraw.xml file from GalleghersArt, version 4.40 1770+ parts working.
Then I started adding parts I missed a model when converted.
So far there where 2 I really needed and by adding these lines in the ldraw.xml file the parts converted just fine!

<!-- Tile 2 x 2 Corner 14719.dat -->
<Transformation ldraw="14719.dat" tx=".8" ty="-.32" tz="0" ax="0" ay="1" az="0" angle="3.141593" />

<!-- Brick 1 x 2 with Two Studs on One Side 11211.dat -->
<Transformation ldraw="11211.dat" tx="-.4" ty="-.96" tz="0" ax="1" ay="0" az="0" angle="0" />

Now, is there a way to stream all work that individuals are doing to one ldraw.xml file?
It would be dumb to do double work (maybe I have done so now too).
