[pattstorage] how to avoid the very long loading time

Hi,
I try to use [pattstorage] to create a multi level preset system
it works fine but once I reach the 3rd level my patcher takes a very long time ( several minutes ! with a complex patcher) to load.
I think it is the [pattstorage] in greedy mode that takes ages to build a path to every parameters, I say so because each time I change the scripting name I got the rainbow wheel for minutes
every thing works fine once loaded, but it is not very convinient on stage

any ideas to improve this amigos ?

thanks a lot

here is a simple exemple, it doesn't takes minutes but enough to see the rainbow wheel and investigate
