I'm guessing you would like that in order to reuse some attributes (locations, recipients, period, etc..) for a different URL when adding many sites? For the record, updown already helps a bit with that by pre-filling the new check form using some attributes from the last created one. So when you create multiple checks in a row, the form automatically pre-fills with settings from the previous one (at the moment apdex threshold, period, locations and recipients). Does this help for your use-case? Are there other fields you would like to be copied over?
