How to use Wix Bootstrap and log parts of the bundle installed

Question

I'm setting up a Wix Bootstrapper installation that installs a number of prerequisites application components (most from Microsoft). Many are x86 or x64 editions of software. Each of those parts will be installed in various default directories. Is it possible to generate a master log which includes all the fragment Exe/msi package installations in the final Software product target directory?
The MyBootstrappedApp.exe /log "Installation.log" does a nice job at a higher level. But I really wanted to ensure the users just click and install, but have the MyBootstrappedApp.exe automatically keep a verbose installation of it and all components. Is this a WIX/MSI limitation?

Here is a sample fragement of the Microsoft Sql Server 2012 x64 native driver installation

The Burn engine does not "merge" log files today. You'll get a log file for the Bundle that can have references to the child log files and log files for each of the packages. However, the Burn engine does provide Variables that will provide the paths to all of the log files. You could then use those variables to create an uber-log file or a special report or whatever you'd like to present to the user.
