I would like to offer more options in the "Conditions" drop down select field when a user adds a new listing. Currently there is only "All Conditions" "New" and "Used". I would like to add more specific items such as
"Used - Like New"
"Used - Good"
"Used -Poor"
Can you tell me what file I need to edit, or where in the admin I can edit this drop down select?
Also, I would like to remove the "ALL Conditions" option because this should not be a valid option. If a person is selling a used item in poor condition, then they should not be allowed to select "All Conditions". It is impossible for an item to posses both new and used condition and will potentially negatively effect search results.

You can update list in functions.php. "All conditions" is probably meant as "Unspecified", unselected, not applicable...

Thank you!!!
