Expose "Beyond Lines" logic for use in filters
The current Element Visibility Override Hierarchy causes Beyond lines to override phasing, which causes some problems. This is compounded by MEP overrides, which aren't even formally documented by Autodesk but sits between Filters and Beyond Lines (ie. MEP linestyles will override both phasing and beyond lines but filters will override MEP styles):

5. Filters
[Not formally documented] MEP Linestyles
6. Beyond Linestyles
7. Phasing Linestyles
...
The addition of filtering by phase (introduced in Revit 2022) is not perfect but is largely effective in solving the problems related to Beyond Lines and MEP lines overriding phasing, however the issue of MEP styles overriding beyond lines still exists.
Obviously some logic to determine when to apply "Beyond Lines" exists within the program, my suggestion is to expose this logic within Filters so that users can apply particular line weights/patterns/colours to these lines on a per-view basis rather than being stuck with the current project-wide setting.
