Override default user / order info before sync

Hi! I have a custom implementation of WooCommerce that uses non-standard fields during checkout (additional emails, additional name and surname, etc.). I would like to use these fields instead of the default billing_email, for example; is there an action or filter I could plug my code into to manipulate and change these fields for syncing with Hubspot?

Also, I’d like to change the format of the deal passed to hubspot to something like %billing_company% – %billing_first_name% %billing_last_name%, is there a filter/action for changing this or a setting in the plugin ?

Thanks!
