Add "exclude" option to display style

How difficult would it be to have an extra option for the display style on the taxonomy page?

Right now the options are:

• default
• list
• custom
• none (hidden)

We would really like to see an option for "exclude" (like CCK display settings). The difference between hidden and exclude would be that with hidden, the variable would still be available to place outside of the "$content" variable if necessary. This is a scenario that I encounter often, and the only work around is to remove the content variable and manually place every field.

Thanks,
