i have my inkscape set up to always open with A4 in landscape, but i need to add a custom page size from the drop down of 12 x 12 inch.

i can see how to make the custom size but how do i add it to the list of available options, i dont want it as my default.

your help would be appreciated please

Create your document then save it into the ..\inkscape\share\templates folder.
