I see no setting in NINA where you can resume adding to your dark frames at a later session to begin with a new frame number instead of overwriting your previous. For instance, I have dark frames numbering 1-20, I want to add another 20 starting at frame#21, if you are starting a new session the progress bar is reset to zero and I do not see a setting to set it to 21. The same thing would apply to adding lights, I am not interested in filling up my file names with time/date stamps when frame numbers suffice. SGP has a provision for this.
Anyone else know the workaround?
