Modify All Label Text in Batch

Hi everyone, is it possible to modify all labels’ text at once? I’m trying to get the length of all silence sections in an audio, as shown in the image below, I generated labels of all silence sections with “Label Sounds”, then I wanted to edit every label and append its length to the text, for example, “Silence 01(0.43s)” and so on. How to do this? I really appreciate it if anyone can help!

You can export the labels as a text file, edit it in any way that you want, then import it back into Audacity.

The correct format for label text files is described in the manual.
