No, it is in the material properties.
File - Prepare - Model Properties
Select change next to your Material
On the right panel is the list of properties: Structural, Thermal, Fluid, Miscellaneous, Appearance and User Defined.
Click on User Defined and your SELECT_JIS_NAME needs to be in that list with a Type value of String and aValue to be set by your relation.
If you don't have this, then you will need to go to your material files and add the parameter and its value.
In the material file you need these lines:
{
Name = SELECT_JIS_NAME
Type = String
Default = '<your value goes here>'
Access = Full
},
