Missing variables in Advanced Conditions dropdown

Describe the bug
The “Other Current State” view in the Advanced Conditions pane lists variables focused_screen_(x|y|width|height) which cannot be selected in the dropdown menu for variable selection.

I would like to use these to implement snap areas with custom ratios (additionally to the default ones, so I don’t want to change them) which work with multiple monitors. If there is an easier option, that would also be great.

Additional information (e.g. StackTraces, related issues, screenshots, workarounds, etc.):
For now, I just use the position of the mouse instead.
