What steps do you recommend to achieve those requirements?

LenoxSoft has a service portal for customers. A Marketing Cloud Account Engagement page action set by the admin will change a prospects engagement custom field to "Engaged" for any prospect who views this service portal page. Customers who visit this portal more often have a higher company satisfaction rate. Those who rarely visit the portal have a high rate of attrition.

LenoxSoft wants to encourage customers to engage with the service portal and has the following requirements:

* Prospects with no Engagement custom field value should be added to the Engagement Program.

* If prospects registers for an upcoming webinar and views the training portal they should be removed from the engagement program.
