Actually i probably find the solution:
You can apply a note template in “Action sets” menu. Of course you need to configure the rules of engagement, but for instance i can set a custom field radio selection to determine which follow up needs to be done, than i can configure a rule that says: whenever this custom field’s value is changed run this action (apply note template) or if you want you can trigger a tag “start button” and then run the automation.
Of course it would have been easier with tag applied based on form submission, but what if my sales rep needs to modify the follow up type not through the form but directly from the custom field of the contact record? I think that this is the case where i can trigger automations even without the form that applies a tag depending on which type of follow up needs to be done.
