dynamically change the number of filtered data of routepass

Hello.

Seems simple but I don't find a way to dynamically change the number of things that routepass can filter..

for example, I have a UZI sending 280 numbers,
I want the user to be able to tell quickly : ok, send 280 numbers but not the 3 the 6 and the 246 (3 filters)
or, ok, send 280 numbers but not the 2 and the 4 (only 2 filters)

the right outlet of rootpass works, but only if you already know the numbers of value to be filtered...

I tried to send a message in the right inlet of routepass with several values in the same message but it only take the first one...

Any idea ?

For information, I was trying to make a simple vst wrapper for live which will easily interpolate between presets whatever the number of parameters of the vst.. It's working well. I just need this routepass thing to filter some parameters to do not be randomized..

Thank you!
