Wish: Historical month-to-month balance reports

I have monthly end-of-month account balances in a spreadsheet, for every month going back to June 2014. Is there some way to add these into HomeBank so I can see them on the reports? If not, can we have a report that shows an account's total balance at end-of-month, in a month-to-month line chart? I would really appreciate it if this is possible.

Thank you!
