From just a regular user like you I would think you could do this like..
Open Control panel and find
Choose the category you like to enable this on
Browse down to, Additional Fields
Find the Add a new field type:
Write a name for this as you would like it to apeare on your site. (Would you like Critique?)
and write in your options like shown
Add a new field type:
Yes||No||only if it's good
You might have to do this by hand to all categories.
From the control panel...
If you would like to add a new additional field, enter the text which will be used to present the options, select the type of input you want to use and then enter the default text or a list of options. Options are entered using a double-pipe || as a field seperator; to enter three options, you would enter: field1||field2||field3 as your Options field.
Then this might not be what you where looking for?
