Trigger for spinning reel

[Nauti Buoy]

With the small diameter of 50 lb. Stealth, I'm looking for a trigger for casting that will save the fingers. Swear I saw one advertised somewhere before, but can't find it now. As I recall, the trigger is mounted to the rod, above the reel, and the line is manually placed over the trigger for casting.
Has anyone seen this and know where I could purchase a couple. I'm looking to set up my 7500SS/8500SS reels with this. TIA.
