How to disable "autofit text" option in LO Impress globally

Hi there,
Every time I start a presentation I have to struggle with the annoying feature that the font size in my textbox is adjusted so that the text fits the box (autofit text option). I know that this can be disabled by right-clicking the textbox in question and I have also heard rumours that this can be adjusted in the master slide.
But I would like to turn this option off FOREVER (and if it were me, get the lines of code deleted forever - having 20 different font sizes is the worst feature ever!!). I frequently use Impress to quickly throw together a presentation and it just costs too much time to adjust this every time.
I’ve seen various different entries from others struggling with this as well and so far haven’t seen a good answer. Maybe this time we can find a solution :wink:
