Adding custom attributes in realignment rule.

Hi Guys,

I have added 2 custom fields in Territory, those same fields I would like to populate in realignment rule.

the below are screen shots for reference.

here you can see Product Brand and Product Type are extension fields added.

The below is the Realignment rule window where I would like to add the above extension fields here. But I am unable adopt those fields here. I can only adapt the fields from account.

Could any body help how I can adapt the fields added in territory to realignment run/rule.

Thanks,

Niranjan.
