Hi Bella'sMom. I have been using a workaround that Craig suggested under a different thread. Again, it's only a workaround but its effective for now.
"In the meantime, while I understand this would be slower, you could also create folders with dates for titles and when you post listings place them in the appropriate folder from the Active Listings page after they have posted. This way the Folder column on the Active Listings page would show the post date of the items and items in the same folder would then be color coded. You can also use an Auto Relist profile, if you are not already, so that when you end the listings they relist based on the profile you create."
Essentially I created folders with titles of the day of the month. I post from my saved listing folder and then look at my active listings folder and use the end early function. For example, today being the 25th, I end every listing in folders entitled 26.
