Can we select value from another business object when create auto complete rule?

Summary:

1、I want to create an auto-complete rule to get a page reminder based on user role and action reason. For example, when a person with role A is changing positions, they will be a reminder that they cannot submit if they choose Lateral transfer, but they can submit if they choose a promotion.
2、I tried to make it in auto complete rule, I chose assignment worker as the business object, when I configure rule logic, I can not choose any filed about roles.
Please help to give some guidance. Thanks a lot.
