Hey axman53, load speed of preset lists has to do with how many presets there are in a list, so the only way to optimize it is to shorten the list. Are you making use of all 99 presets in a list? Would it be possible to organize your show to access a different portion of the preset list? Example – Songs 1-5 use preset 1-10. Songs 6-10 use presets 11-20, or something to that effect.
