How can I open a tdms file and replace a subset of data then save that change without re-writing the entire file again?

Hi all,

Is it possible to open a tdms file and make a small change an an array subset then save the file without having to save the whole dataset as a different file with a new name? That is to say, is there something similar to "Save" in MS Word rather than "Save As"... I only want to change a 1D array of four data points in a file of 7M data points.

I am not sure if this make sense? Any help is apreciated.

Thanks,

Jack
