I was about to make a post asking for the same feature when I saw this post from two years ago! The amount of manual data manipulation without this feature is tedious and time consuming. Proposals/Opportunities should have as many filters on Export as all other fields to prevent users from having to come up with clunky workarounds. Please add this to the export features on the Total Web Solution.

There should be more options for which Proposals/Opportunities you want to export. Especially active/inactive right now you only have the option of purpose. You should be able to sort which one exports first as well.
