How to create User defined attributes List of values dependent by proj_element_id which is part of p

Hi,

We want to create a list of values which contains only informations entered at a specific proj_element_id level.

We know that we can use the following to create dependent value sets of another attribute group or to a primary key, but how can we use the proj_element_id to select only those values?

 This is for values dependent of another attribute group:

:$ATTRIBUTEGROUP$.<your attribute's internal name>

Also, to refer to a primary key for the object to which the attribute group is associated, the  :$OBJECT$.<the object's primary key column name>  should be used.

Thank you,
