I am writing a long procedure and instead of re-creating the alphanumeric list each time (having to format etc) I want to create a style I can apply whenever I need to use it. however, when I do that, the letters or numbers just continue instead of restarting at 1 or a in a new section:


Heading 1:
a
b
c
Heading 2
d
e
f

I want it to be:
heading 1
a
b
c
Heading 2
a
b
c

What do I need to do in creating the style to tell it to start over when there is a new section?
Thank you
Michelle
