Searching images while in campaigns

It would be very helpful if there was a search bar to search for stored images when you are setting up the campaign.

We use a  lot of created flyers for our distribution emails that we upload and place in our weekly emails as images.

We have a lot of images and it becomes very cumbersome looking for the image you need.

I have created a FOLDER for FLYERS, but it is based under all folders.

Is there a way to set up a folder under IMAGES so that we can search in that manner.

Any help would be greatly appreciated
