[LH3937] No ability to set custom page size

There appears no ability to set custom page sizes in Page Setup which IMHO is a major miss.

I’m Fortunate in that I have Mac and Win and can make a custom size in Mac, however have not yet tried to see if a custom size set up in Mac will transfer to same project being edited on Win. Don’t want to end up with a mess if it goes wrong.

This has been filed. Thanks.
