Is it possible to alter the format of each cell so it stays that way when first opening Libre Office writer?

I always like to have cells formatted to print the information in the centre/middle.
Every time I open a new copy of Libre office calc I have to format the cells to do this.
Is it possible to do it once and save the result so it loads like that when I next open libre office calc?
Thanks.

You can edit the Default style (or better, create a template).
Take a look at Alignment and Value Highlighting.
