How to add multiple strings to a keyword field/list variable

Within workflow manager, within an assign data node.

I have 5 variables that I would like to add to a keyword field with one line of code in the arithmetic expression, instead of adding them one by one.

so something like
add(DW_STUDENT1, DW_STUDENT2, DW_STUDENT3)



Thank you
