How do I delete imported photos on the iPad in less then 2000 clics?

Hi.

I've been using the iPad to collect photos form my digital cameras.
I have a few thousand of such photos on my iPad.

Today I wanted to delete them (because they take a lot of memory and are synched anyway after correction).

I could only find how to delete them by selecting them one by one on the iPad .
On the Mac, I use Aperture, which has no option (AFAIK) for deleting imported photos.

How stupid is that that you can import thousands of photos on the iPad and not delete them in under 1000 clics?

I just found out that I still have iPhoto on my Mac, so I am going to import pictures from the iPad to iPhoto and use the option to delete them.

Anyone with a less ridiculous solution?

Thanks in advance,

Jerome.
