Pop-ups on taskbar. can they be slowed?

[pdes]

When you touch an app icon in the taskbar, the associated windows' icons pop up. With Outlook for instance, there could be many of the window icons that fill up the bottom of the screen. However, they vanish within a second, often too soon to be able to select the window you want.

Is there a way to stop these icons from automatically vanishing or at least, slow them down by a few seconds?

Thanks
