Alternative Index Comparison/Benchmarking

Currently the only comparison available for my portfolio returns is the VWRL FTSE All World ETF. This is available in the insights section of the app.

Since I invest in mid cap+ US and UK based equities, it would be great to be able to change this to something developed market focussed. Or alternatively be able to choose between the S&P and FTSE.

A drop down menu with several indices would be a preferred option.

I looked through the forum to see if anyone has suggested this. I may have missed it so if there is already a suggestion I would be grateful if someone could send a link.
