Thanks.  I loaded the TCA but didn't know about ds_pointerField, I'll 
try that.

Yep, that's where I had it.

Maybe it would be possible to load the existing xml from the TCA and 
modify it with XPATH or something?  Then I would have to write it back 
out to a temp file, or can I store the XML in a variable?

Too bad, that would be really easy.  I don't understand the reasoning 
behind the flexform xml format, you need to define a specific index for 
each thing and update it manually--this seems unnecessary to me. 
Perhaps this can be changed in the future!
