Recurring price setup in CPQ for OCC - CPQ integration flow

Summary:

We are implementing OCC - CPQ integration. Using CPQ as external configurator. CPQ only for configuration flow not for quoting flow. We have some part custom fields mentioned in the guide to send the recurring price, frequency, cost to OCC. We are able to send the value by updating these field values in parts database. which is something hard coded in parts DB. But we need to know how we can make this fields dynamic value without any hard coded value. Is that possible to make it dynamic fields? If so, how it can be done?
