Smush.it Plugin - Smush all images again

Hi

Thx for the Smush.it plugin, it works great. I just made few mistakes in settings, so I did not smush all pictures completely, but the plugin considers them as already smushed.

Can I smush all pictures in my media library again with current settings?

Some pictures are also not able to smush more than 5%.

Thx for soon answer.
