Yes. Text me privately.

I did something on a very simple basis by creating a form (not seen by users) that had fields to store the history information, including a field to point back to the entry it's related to.  Each time someone updated a record that needed its history tracked, PHP code added a row to this "history form" by using frm_after_update_entry (https://formidableforms.com/knowledgebase/frm_after_update_entry/).
