Affinity Publisher - change colour of "out of bounds" area

[poseidal]

Hello, is there any way to change the colour of the 'out of bounds' area on a document? Currently for me, it is a middle grey, which I find difficult to use as the cursor vanishes easily on this colour, and when placing elements here (outside of the document to work on / resize before putting it into a visible page) it can make it harder to read/see. In addition, the bleed outline border is hard to see on it. Is there an option somewhere to change it to white, or light grey so these elements can be seen more easily?
