Hello Brian,
Thank you for your questions.
To change a lead time, just add the snipe again. You don't have to delete it first. There isn't enough area in the card to put a pull-down for this. We'll se if we can when we release the mobile-friendly site early next year.
To import your Watch List, there is a button on your Pending tab.
Please let us know if you have any other questions, or require other assistance. We are happy to help.
