How do I import the STATUS field when importing items?

How do I import the STATUS field when importing items?

We have had a Zoho Invoices account for some time now and have compiled a very good list of items inside that account. We have just started a new company and opened a new Zoho Invoices account for it. 

Because what this 2nd company does is so similar to the 1st, I exported all the items from Company 1 and imported them into Company 2 account. Unfortunately though, there doesn't seem to be any way for me to import the STATUS field of each item, which makes the whole feature a lot less useful.

I know that the field  "status" is being exported, because at the end of my importing process I even get a message from ZOHO that some fields have not been mapped and aren't being imported, but how do I map them?

Btw, if that matters, I am using CSV format to do the import/export.
