How do I add security updates to Creative Cloud Acrobat DC?

We recently started our membership with Creative Cloud.

When I built my new package, It downloaded Acrobat DC and included the latest security update at the time.   Yesterday (3/8/2016), new security updates were released.  I thought if I went into Creative Cloud Packager and edited my package, it would download the new security update.  It seems that this is not the case.

What is the best practice for updating the package with current security updates?

I see the installation files for Acrobat DC are at [packagename]\Build\Setup\Apro15.0\Adobe Acrobat\

Is that an installation point that I can directly update with the MSP using msiexec /a [path to AcroPro.msi] /p [path to security patch]?

I couldn't find any documentation on how to do this, and it just seems weird that the Creative Cloud Packager will give you the latest security update when you build a new package, but won't update the package when new security updates are released.

Thanks in advance for your help!
