Prepopulating select list custom field

[Suheel Hussain]

I am importing a CSV file, and have designated one of CSV column as custom select list field. After the import the selection list entries are that present in CSV file. How do I add more entries into this custom field?

Not sure if I understood it correctly, if you mean adding more options to the field, here is how you do it.
