Is it possible to bring the Customer attribute in the Shopping cart price rule section to make a conditions like catalog attributes are showing in the promotions page( use for Promo rule conditions).
With Magento Enterprise you can do this but it requires 2 steps.
1. Customer segmentation
In the backend go to
Customers > Customer Segments and create a new segment.
Choose a name, the websites it should be active on and make sure it's active. Now
save and continue edit it and add conditions.
2. Shopping Cart rule
Now go to
Promotions > Shopping Cart Price Rule in the top menu and create a new rule.
On the conditions tab you can choose
Customer Segment as condition and pick the segment just created
