promoted parameters dont have python callback script

[pelos]

I have a vopsop node  and I added a ramp parameter and a couple other toggle parameters,

 

since this ones are automaticly promoted by Houdini,  they do have lines to disable, hide, and a callback script,  but doesn't let me change the option to python.

 

so I manually edit the interface, I added a toggle and a ramp parameter directly to the UI.  this params  have more options than the one that Houdini promoted.    and I am using this ones as temp parms.

 

the temp parms have a script to modify the normal parameter and the other things I wanted to do from the beginning.

 

example:

 

ramp1    ramp manually done         call back script,       copy paste this ramp into the ramp 2  + print "hello"

ramp 2   ramp promoted by Houdini  this one is hidden and use in the vop sop.

 

 

is there a way to be ale to tell the promoted parameters from Houdini to use proper callbacks?
