I am looking for an addon that will auto register for a SNG when my open tables drops below a certain number

ie i want something that will keep registering for 2 or 4 games constantly (similar to sharky strator)

but i do not need it to filter out people in any way

i just want it for low and micro limits and to only sort by game type (or by shown game if i filter the game type inside pokerstars)

would prefer it to be a free to use or 1 off payment type addon

does anyone know of such an addon
