Open up bullet options & lists to include letters

I would love to see the following "LETTER" options implemented into Articulate.

In a numbered list, you can edit the number.  I tried to input a letter.  Hoping it would work.  It did not, 😟.  The idea was to have my image large on the screen.  The image has "Letter" identifiers on it.  Having the numbered list that could be used with letters would be great.  

Offer a LETTER option for bullets too.

Sincerely, JT
