Is it possible to have an admin-configurable activity stream prompt (changing the “What’s new ______?” to something custom)? The only way I can find to change it currently is to manually edit the theme, which is a bit of a pain if one can’t access the site’s files.

If you can’t access the site’s files, than there is nothing really you can do.

You need to edit a php file in your theme to do this.
