Is it possible to have the following permalink structure? {CATEGORY_NAME}/{ITEM_TITLE}_i{ITEM_ID}
The current structure {CATEGORIES}/{ITEM_TITLE}_i{ITEM_ID} enqueues all the parent categories and makes the URL too long. But many classified sites have found a hack for this to make it shorter

Try just CATEGORY keyword, but not sure if that one is supported. Could be added in next update.

It was specified below that which doesn't show the keyword {CATEGORY}:

Accepted keywords: {ITEM_ID},{CATEGORIES},{ITEM_TITLE},{ITEM_COUNTRY},{ITEM_COUNTRY_CODE},{ITEM_REGION},{ITEM_CITY},{ITEM_CITY_AREA},{ITEM_ZIP},{ITEM_CONTACT_NAME},{ITEM_CONTACT_EMAIL},{ITEM_CURRENCY_CODE},{ITEM_PUB_DATE}

Seeing that changing permalinks can cause significant change, we are thinking it is important we are sure what will be the outcome of the change.

Then not available.

Ok.

Will it be available soon?

Because, this is very important as competitors are making use of these hacks.

They can have up to 4 to 5 levels of subcategories but when you check a listing in the very last category, the link only shows,

{City}/{Current Category}/{Listing Name}

It will be available in next update.
