It is possible to delete history with macro?

Hi guys, I’m new here, and still learning about audacity.
I’m using version 3.0.3 for Windows (10).

Well, I recently discovered the MACRO function, which was a lifesaver.
However, I have a problem. I created a Macro to transform 5.1 audios into 2.0 with a specific volume setting for my TV and some effects that I think make MY experience when watching files better.

The MACRO function helped me as I can leave the program doing everything by itself while I go to work or sleep.
Macro worked perfectly, however, leaving several tracks being processed at the same time, I ran out of storage space.
I would like to know if there is any way to make, after a number of steps, MACRO delete the audacity history, leaving only the current state, recovering storage space.

No there isn’t, but the history is automatically reset (cleared) after each file has completed.
