"Keep Additional Frames" wildcards?

[ScottIngram]

I just installed a few addons that spew a bunch of frames onscreen (LS:Toasts and Silver Dragon) that I'd like to keep visible during the "Situations -> Dragonriding -> Fadeout UI." I can do so fairly easily via the "Keep Additional Frames." However, the frames spawned by these other addons have no common parent frame and all have unique names. For example, SilverDragon1 and SilverDragon2. So I have to spam my list with a long list of possible frame names.

Request for new feature: make it easier to specify unique but similar frame names. Maybe let the user specify a wildcard, like "SilverDragon*"
