It is not possible to define your own status values
does not support integration of custom status types with built-in status types. However, if you prefer to use a different method of keeping organized, you can create standard comments for each a contact in the Comments section under the contact's Summary tabcomments section of a Contact Summary view. To find all the contacts of a certain classification, use Find Contacts to search for any contacts based on the comments you entered. In effect, this lets you make unlimited contact groups of your own design.
