Cash Accounts - select per trade

Tag transactions by broker

Sharesight doesn’t seem to have the ability to tag transactions against a broker, which makes it very painful to reconcile holdings if you hold an asset across multiple brokers. Custom groups and labels don’t work as they are across all holdings - i.e. not at a transaction level. Any solutions? Any update from Sharesight on a fix for this?
