I need to create two content types (Call List and Call Announcements), in Call Announcements there are 5 fields, in Call List there are 12 fields but 5 of them are mutual with Call Announcements, I do not want to create 2 different content types (Call List, Call Announcements) because when the user create a node, he should be able to choose where the node is shown (in Call List, in Call Announcements, Both). (Call List and Call Announcements should be in the same database table)
How can I do these?
