Variable list allows you to have one entry out of a list. As a variable list, the user can add entries that ar enot in the list.
You should be treating the custom property as a string and enter values such as "lpar1" or "lpar1, lpar 3". If you enter the values in a standard format with standard delimiters, you could split the single column into multiple columns by using Excel's Text to Column command.
