Assigning parameter to multiple categories

#I’ve been able to assign a multiple parameters and parameter values to multiple elements, but only to one category (e.g. walls).

#Is there a way to combine nodes, or a python code to assign a parameter to multiple categories (e.g. walls, floors, columns) at once? See python script below with 4 inputs (0,1,2,3):
_paramName = IN[0][0]
_groupName = IN[0][1]
_paramType = IN[1]
_visible = IN[0][3]
_category = IN[2]
_paramGroup = IN[3]
_instance = IN[0][6]

Good morning,

Do you finally find the solution in order to set several categories at the same time?
