Different default Style Set for new emails and to notes in new contacts, appointments and tasks of Microsoft Outlook

Question

I formatted a Microsoft Outlook 365 email in my PC the way I want all new emails to be formatted by default. (An example of such settings: The left and right margins were set to 3 cm.)

Then, I saved the setting as the default: Format Text → Styles → Change Styles → Set as Default.

I also saved the Style Set with the name "Emails" and the extension dotx of Word Templates: Format Text → Styles → Change Styles → Style Set → Save as New Style Set → Emails.dotx.
In the folder where Outlook led me to save Emails.dotx, C:\Users\rodol\AppData\Roaming\Microsoft\QuickStyles, there was another Style Set, Outlook.dotx, that I had created or modified in the past.

I was a happy man until I created a new Contact. When I wanted to add some notes in the Notes area, I was unhappy to see that the 3-cm margins appeared there. I had to open my old Style Set by the name of Outlook.dotx to fix the formatting. (Same story with notes to Callendar and Tasks items).

Is there a way to have a Style Set for emails and another for notes to other items?

If not, is there a way to add an automatically executed macro to change the Style Set of every new mail?

If not, is there a way to add a shortcut to choose a specific Style Set?
