Editing listings with inactive package

For a package which is made inactive, existing listings with that package will remain published until they expire.

However, it seems these listings cannot be edited either from the front end, or by admin, or by import – in case say some change in the post_content or any custom field is necessary.

Is there any way to edit such posts on inactive packages as they may have a long lifetime remaining but the package is deactivated maybe due to a pricing change?

thanks, Vivek
