it depends a little bit on your way of working, I will tell you how I do it:
1) In the 'Edit/Preferences' from the main menu click 'Advanced' tab and open the 'Option Inspector'. 2) Look up 'CounterIncrements' or open the group 'Formatting Options' and open 'Automatic Numbering' and double click 'Counter Display Options' 3) Change the 'Show Option Values' from 'Global Preferences' to the notebook (that is open), and where you want to make the changes. 4) Change the 'CounterFunction' to one of those of the drop down list or set it to 'Other Mathematica Function' 5) Change the function by double clicking into something like:
From now on the i-th equation number will be formated as the i-th entry of the list you specifiy in the function above.
I use this way to control the formatting when writing books or articles in Mathematica.
Hope that helps,
PS: The double clicking to change the function is a little bit tricky (M9, Ubuntu 12.04), just try as long as you find the function editable.

Is there any way to format how equations are labeled in notebooks? For example, using the "DisplayFormulaNumbered" puts numbers on the right of equations, but is there anyway I can format these numbers? Say I want an equation called (1a) and (1b) or something instead of (1) and (2). I've been messing around with trying to edit the stylesheet to no avail. > > Nick >
