Global Seamless Changing

i would like to be able to change all of my presets to seamless or not seamless by some sort of global switch that would turn them all on or all off with one click and would then save them this way also.

maybe each preset could have a little check box like in the download library (the old style) where you could simply click on a preset to include this one or not for the global switching. seems like a long way to have to render each preset out before changing it to seamless or to turn seamless off. i suppose you'd still have to render it, but maybe you could save some time by not having to display the rendering while it's going on.

the little checkbox could also be used to globally change any of the other sliders and checkboxes, too. move one slider on one preset and it would move that slider within all the other presets, as well. again, not sure if this is feasible or would save all that much, but at least in my head it seems like a good idea
