Process variable length comma separated lists within cells

Given a decision table column:

VALUE1, VALUE2, VALUE3
VALUE4, VALUE5

It is required that a DRL snippet could be constructed to utilise all available comma separated tokens and not have to hard code $1, $2 etc references.

Eg a snippet could be:

property == $forall_param_and

resulting in the compiled snippet:

property == "VALUE1" && property == "VALUE2" && property == "VALUE3"
property == "VALUE4" && property == "VALUE5"
