Create Multi Level Bullets in Campaigns

[SloaneS70]

Hello- Is there a way to have sub-bulleted lists without having to restart a list?

i.e. I would like to use a numbers list but then have sub-bullets that are either little letters (a, b, c, etc) or plain bullets and then be able to go back to the main list. Right now the list starts over when I add a sub-bullet. 

Also the ability to have line breaks between a numbered list would be ideal as evidenced below. This doesn't work in the email template.

Having the ability to have indented bullets (nested lists) would be very helpful. The bullet feature as it is now is great, but the ability to have more than one level would be even better. For example I have the ability to do more than one level here in this New Idea post:

• Level One
  • Level Two
    • Level Three
