Uploading three fields to one multiselect list?

[Asinproject]

Within my accounts, i have created a multiselect field for the organizations category. I now have a CSV file with which I would like to import data into my contacts. How do I map three fields in my file to the same list in my accounts tab?

For the multi select fields you need to set the values like that:

Option1^,^Option2^,^Option3.

Where Option1, Option2 and Option3 are the dropdowns keys, not the label displayed on screen.
