Bulk Select/UnSelect Clear (Q Mac)

You can already do this! 😀 You can select two or more transactions, and once they are highlighted, Control-click and select "Set Status of selected transactions to" from the dropdown menu, and select either "Cleared" or "Not Cleared" depending on what you are wanting to do. Or select multiple transactions and pull from the main menu, pull down "Transactions > Set Status to" and then select either "Cleared" or "Not Cleared".

To select multiple transactions, you can Command-Click on each one. To select a group of contiguous transactions, you can click on the first one and then Shift-click on the last one, and everything in between will be highlighted. (You can then add to the selected group of transactions by Command-clickng on other transactions; you can also remove selected transactions from a highlighted set by Command-clicking on a highlighted transaction.)
