I can't add StatusCode field to forms and views in List Entity

Question

We are using Dynamics 365 Sales. Its version is 9.2.21073

I try to add statuscode field to forms and views in the MarketingList entity. But I can't see that field options like below.

StatusCode of other entities can add to forms. How can I add the field on the form?

Answer 1

It might already be on the form.

The default is to only show "unused" fields. There is an option to turn that off
