This is a feature I requested quite some time ago, and at that time, there was an encouraging response from the development team, but I would like to raise it again because it has become a critical need for reporting and business intelligence purposes.
Currently, Custom Fields can be added to most entities in Manager, but not to the Chart of Accounts, i.e. not directly to the Balance Sheet and Profit & Loss accounts.
Being able to assign Custom Fields to accounts would open up enormous flexibility for BI tools integration (e.g. grouping and filtering data dynamically) and multi-dimensional reporting.
In my use case, this would be fundamental to drive automated BI reports and analytical dashboards connected to Manager’s accounting data.
Please consider this enhancement with priority: it would greatly expand Manager’s analytical capabilities and make it much more powerful for professional and enterprise users.
