The functionality to view the routes in WME already exists. You can click on the links from within WME...but for new users, it's a chicken and egg conundrum. All they have to do is get those links onto the Dashboard page.
Then there's the whole Alternate Name field, which some editors spend a lot of time filling in. That data may or may not be useful when they finally make an alternate name field or shield field in WME. I don't see any way that they're going to be able to differentiate between shield numbers and alternate names and we're going to have a lot of new work to do once that change occurs.
Personally, I don't do any alternate naming. I'm working on getting the highways in Louisiana the way I think they should be (consistent), and whenever the new alternate naming/shields come into play, I'll have a pretty easy time of doing a Select All and filling in the data. It won't happen overnight, but at least I won't have to spend a lot of time going segment by segment all over again, as I'm doing now.
