Overall Portfolio Return Metric

Is it possible to also show a Money Weighted Rate of Return for the specific portfolios (ISA, Invest, CFD)
The return that is shown by the graphs currently is meaningless as it shows only the current return based on current investments.
It could be a simple XIRR calculation with the inflows and outflows.


It would be good if it showed two metrics, amount invested to portfolio, and overall portfolio value.
