I have an old portfolio and can’t access email account but got access to this email account

It would be helpful to have this as a all portfolio view so -

As a user I would like to see all assets I hold in one view and understand their performance so that I can know my overall position.

Acceptance criteria -

All assets held across portfolios are shown

All assets performance is calculated

This should be view only so assets are not allocated to this instead of correct portfolios
