Update application content after a SCCM 2012 SP1 restore

[MeMyselfAndI]

I'm testing the restore scenario of SCCM 2012 SP1.

I followed this Microsoft guide:

http://technet.microsoft.com/en-us/library/gg712697.aspx

 

There's a topic "Recover Content Files":

Update content: When you start the update content action for a package or application deployment type, the content is copied from the package source to the content library. The package source files must be available in the original location for this action to finish successfully. You must perform this action on each package and application. For more information about updating content, see the Update Content on Distribution Points section in the Operations and Maintenance for Content Management in Configuration Manager topic.

 

Does this mean that I have to right click on every application deployment type to update the content?

We have a lot of applications, this would take me ages to do!

Is there a way to update the content of all the applications at once? Maybe with a script?

 

Thanks in advance!
