Keyscape always reload samples for User patches , but not Factory patches

Hi everyone !
I want to use my user patches in Keyscape , but when switching from one user patch to another , it always reload samples , even if the patches share the same samples set . For example let’s say I create a patch with the rhodes classic with chorus effect on ,then create a patch with phaser on . Then , when switching from one patch to another , it always reload samples .
BUT ! When you go to factory patches , if you switch from (for example) “Rhodes classic chorus” to Rhodes classic Ballad , the change is instantaneous , no reloading ! For live usage , it’s sooo damn convenient !
Has anybody found a way to get that same behaviour when switching user patches ?
Thanks guys !

Sounds like a question for Spectrasonics…
