I want to add anniversary, class of apartment, LMR paid. Where i can add this additional information?

Hi there, 

Nice to hear from you again. I've just responded to your other question regarding additional customer details. If this is what you're referring to, please take a look at the instructions I've provided here: Where is additional information tab in new customer?

If you're looking for something else, can you please provide some additional details of what you're trying to do?

Let me know if you have any questions.

Cheers.
