Default Font replacement

[JohnPaton]

I have changed the default Font in Writer. But how do I do so in Calc and Impress and make the changes permanent. It is a real pain to have to use Format-Character all the time. Libre Office 3.6.2.2

Please take a look to this thread.

In Calc: Where is the custom default formatting setup?

I need all cells to be always formatted by default as Vertical=middle and Horizontal=center alignment. If I select all cells and then set this formatting, it will change back each time I erase or delete cells etc and I have to do it again and again each time -a frustrating torture! So where is the custom default formatting setup, or at least an ini file? Does it exist? If not, this is a serious omission, like omissions found in software made by amateurs.

Many thanks to Oliver for his clear explanation. Not only did it solve my immediate problem but I learned something about Style, Formatting and Templates as well.
