Can I use custom Opportunity or Opportunity Revenue attributes in Territory assignment?

Summary:

How can we use custom Opportunity (or Opportunity Revenue) attributes as Territory assignment Dimensions?

Content (required):

We have 4 custom attributes in the Opportunity that we want to use as Territory Dimensions. They are all Fixed Choice List (FCL) fields. We enabled Extension Dimensions and mapped them to the FCLs of the custom attributes.

But, in the Manage Sales Assignment Manager Objects task the custom attributes are not on the list of attributes that can be added to the mapping.
