Feature Request: Monitor Site Property Timeout & Retry

I have one IoT device that takes about 20 seconds for the site to load in a browser. In Glance, it always shows as error when setup in a Monitor Widget. Would it be possible to add a timeout value for a site setup in a monitor widget to be able to specify a timeout value so that it waits for a user specified time before reporting it as an error? Might also make sense at the same time to also add a retry value so it could be tried 2 or 3 times before reporting as an error.
