preload samples into sfplay~

Im trying to create a drum module that will play different samples according to what note and velocity is being triggered. i have just about finished the patch and each sample has its own sfplay~ object. as their is over 500 samples for a drum kit i want to get the samples to all load up automatically by just locating the folder using open dialog fold object box. any ideas how this can be achieved i am using max msp 4.6.
