No. Custom reports include details of individual transactions, not account balances. (Balances are processed results of a defined set of transactions.) You can obtain totals by grouping with appropriate report design. But those will not be account balances.
But there might be other ways to get the information you seek. Many of Manager’s displays include running balances; and those can be copied to spreadsheets. What exactly are you looking for?
I’ve configured a report as attached. (It is a totally fictitious business and fictitious names therein!) In far right hand column, I would hope to show a balance for each line. So if in the attached next line were a debit of $400, bal shown in far right column would be 300 CR.
Thank you so much, Iubus. Will study that past thread (and the published guidance). I do think as to that which I’ve done so far, an easily understood report can be produced, especially if you give a good heading to the far right hand column, such as “Amts & final bal held in trust for you (Cr) ($)”, as below:
