Diffing two binaries should have side-by-side disassembly when drilled into a specific function

I have been doing some binary size analysis to determine where some growth has come from. A certain function increased in size from 3.1KB to 3.9KB. Exactly what part of it grew is not obvious. It would be super helpful if the comparative analysis view of a function had the disassembly for both sides (ideally with highlighting of differences). That way I can see exactly what is different and spend my time making it better instead of spending all my time trying to spot the difference.

In practice I had to open 2 copies of SizeBench in non-comparison view to see the disassembly. This was manual and error-prone and I did not enjoy it.
