Is there a way to download ALL app updates at once in Amazon App Store? Device: Verizon Droid X
Androrid: stock Froyo 2.2 ROM
Amazon Market app: latest version (updated 3/3/2013)

When I open the list of apps to be update in Google Play Store, there is a button on top right which lets me download and install ALL updates at once, instead of doing it app by app.

Is there such a capability in the app for Amazon App Store?
On the Kindle Fire, on the list of apps to be updated, there is an Update All button at the top right. You can update one-by-one or all-at-once, but there's no facility to update a selected group.
