Xero Create Item module - how to create untracked item

I’m successfully creating items in xero, however they have the ‘Track Inventory Item’ set to true. In the make module there isn’t an explicit ability to control this. I’ve tried setting the Account to empty (and not Inventory), however Make then throws an error. It seems that the tracking is set to true by default and therefore the account field can’t be empty. Anyone know a work around?
