Never mind. Finally, finally found it.
X2 Customization and Form fields.
I've tried many CRMs, and this one by far is the best. Sorry for the post, I had searched and searched and finally...
To add, I had used X2CRM 3-4 years ago and updates stopped and had me concerned and started using a paid one. Finally noticed it was back in the update "business."
Hope it never stops.
