Append an array inside a mat file without loading

Hello, I was wondering if anybody knew of a way to append an array (in this case, a struct array) that has been saved to a mat file without loading the array into memory first. Here's a simple example of what I mean:

1) Create a struct array in a .mat file:

myStruct(1).name='Measurement2'; myStruct(1).type='double'; myStruct(1).value=2.3; myStruct(2).name='Setting'; myStruct(2).type='text'; myStruct(2).value='High'; save('myFile', 'myStruct')

2) Do other things (close Matlab, have coffee, load new data)

3) Look at new data

newStruct.name='Color'; newStruct.type='text'; newStruct.value='Blue';

...how could this get saved as an append to myStruct (e.g. myStruct(3)) inside myFile.mat? The -append switch on the save function causes the entire myStruct array to be replaced by the new one, which I do not want.

Any help is greatly appreciated, thanks!

The answer is no unless you've got the latest and greatest version of MATLAB.
