Any way to stop Pro-163 from skipping over Astro?

Title says it all, is there Any way to stop a Pro-163 from skipping over P25 on a smartzone system. There has to be some kind of hack or trick right? Maybe a firmware hack? I know its only the header that tells the type of transmission, could messing with the delay settings help?



I was also wondering about the PSR410 for EDACS ESK with provoice but that's another board.



I'm trying to test out DSD+ and it would be nice to not need to scan in conventional.
