Is there a way to update certain fields when sending emails via Copilot?

Hi,

We are using Copilot to send our NPS survey and I would like to update a field on the Customer Info level to hold the date of the last NPS survey that was sent to the account.

Is there a way to update fields automatically when an email is being sent via Copilot?

I was thinking to use the rules engine , but which object do I need to use?

(Not NPSSurvey Response because then the field will be updated only for those who sent their response and not to all the power list).

Thank you,

Aviv.
