How can I add multiple custom libraries to the Simulink library browser on top level?

I would like to add multiple custom libraries to the library browser at top level. How can I do that?

To add multiple custom libraries to the Simulink library browser at top level one needs to save the appropriate libraries to the same directory.

Now "slblocks.m" can be modified as follows to add multiple libraries from the same directory: 

blkStruct.OpenFcn = {'Library1','Library2'}; 

Browser(1).Library = 'Library1'; 

Browser(1).Name    = 'Library 1'; 

Browser(1).IsFlat  = 0;% Is this library "flat" (i.e. no subsystems)?

Browser(2).Library = 'Library2'; 

Browser(2).Name    = 'Library 2'; 

Browser(2).IsFlat  = 0;% Is this library "flat" (i.e. no subsystems)?

blkStruct.Browser = Browser; 

For example, 

matlab\toolbox\simulink\blocks\slblocks.m

identifies both the Simulink and and Simulink Extras libraries.
