Mass Edit Custom Fields from Search

Hi!

I'd like to be able to mass edit custom fields based on search results. This could either be by adding "custom field" in the List View's mass edit menu or by making it possible to view search results in Table View. 

Use case: we use blueprints.... a lot! And sometimes we need to go through each project launched from that blueprint and make changes to particular tasks. In order to configure a calendar, we might add a checkbox to certain tasks that are repeated across all of our blueprints. One blueprint we use a lot has about 160 tasks on it. We can't dig through those 160 tasks for all 40 launched projects to update all of those custom fields. We need to use the search feature to target the task name, and then mass edit a custom field on all 40 tasks that have that same task name.

Adding custom fields to List View's mass edit menu would have the added benefit that you'd be able to do it when you're working on a project as well or when you go to List View from a dashboard widget. I know you can do it on Table View, too... but sometimes it's a little glitchy. Sometimes it doesn't copy it when I hit "ctrl" + "c" when I've selected a field and I have to try it a few times before it works.
