I'm working on adding the ability for an admin to run a manual transaction for the user in the dashboard with the E-commerce Add-on. I'm figuring the best way to handle this would be for the admin to be able to select the option from the dropdown in the Search User panel, and also as an option on the toolbar of the View User details page. What would be the best way to add an option that would redirect the admin to a custom single page in the dashboard?
