Voila! it works!
Not exactly an original idea, but I went to Lowes, got 2 ft section of 3 inch ABS tube. 2 plastic snap fit drain strainers as end caps, attached mini bungie to each cap to hold them together from the inside (in a hole at the edges), 2 more mini bungies from hole at opposite sides of each cap and attached to anchor trolley. Pull on either cap to allow a bait to come out (cap rests neatly on the side of the tube, and then allow it to snap back together. Didnt even have to drill holes as the flow from the strainers is adequate, but I may drill a few in the tube body just for the heck of it.
