If you ever want to delete multiple items across your portfolio you can do it now from one place. This section is called Bulk Delete and you can find it by accessing Settings in the bottom of your left-hand side menu.
After accessing that section you just need to select the type of entity you want to delete e.g. Bank Transaction and then you can also narrow it down to a specific timeframe.
Below you can also find the filter which can help you to narrow the selection.
In the next step, you just tick boxes next to the items you want to delete, put a description at the bottom of the page and press Delete selected items. The example below is for deleting multiple bank accounts and shows the screen just before clicking the delete button.
If you have deleted anything by mistake you can always restore it using Undelete Items.
