you need to be a bit more specific ... as Chip said, it's definitely 
possible to "combine" providers, but depending on what you actually want to 
do, this may look like:

provider1
{
	self->watchit=1;
}

provder2
/self->watchit==1/
{
	/* record data */
	self->watchit=0;
}

or

provider1,
provider2
{
	/* record data */
}

  ...
