Exam Certified CPQ Specialist topic 1 question 41 discussion

The Universal Containers Admin is creating a custom formula field, Approval Score, on the Quote Line object to calculate approval score. This field will calculate the average approval score for the Quote to determine how many levels of approval the record should go through when submitted.
The Admin planned to use a roll-up summary field on the Quote to average the Quote Line Approval Score field. The Admin received an error when attempting to create the field. The Quote object has too many roll-up summary fields.
In addition to creating a custom number field on the Quote object to capture the average Approval Score, which CPQ functionality should the Admin use to resolve the issue?
