Add to the trading grid some identification of a trade that was created either by importing from a broker, or by importing in Monery format or manually. + Option to filter this e.g. trades from XZB only, IBKR only, etc. Ex: Once XTB Changed the import format from CSV to XLSX, the solution on your part was to delete trades from XTB. However, I have the same ETF traded through other brokers, so it wasn't about deleting entire tickers, but only specific trades. By doing an Investment Plan/DCA on XTB I have several hundred purchases in there and I have to gradually clear them manually. I also have DCA on another broker. I can't simply delete, completely portfolio and simply import, from all brokers again, because, I have to rewrite some of the tickers to get Monery to accept them and that would be even more work. This would make it easier for me to do a few hours of work.
