Custom Reports Capital Accounts

Is it possible to write a custom report for one or all of the Capital Accounts showing every transaction for each Capital Sub-Account? This would be very useful report for a superannuation fund member showing, on one page, details of Opening Balance, Contributions, Taxation etc

It does not seem possible to select Capital Sub-Accounts in Custom Reports?

Maybe this could be a standard “Capital Accounts Detailed” report under the Reports tab.

I suspect what you want to do is part of this idea
