I had a class on emails in NXT and noticed that the fields are somewhat limited making personalization limited. Would it be possible to add the following?

1 Salutation. I have many member records for couples and need to address them as Mr. and Mrs. XYZ in emails

2 date joined

3 date dropped

4 Credit card type used for their recurring gift

5 Credit card expiration date

6 last 4 digits of credit card
