Question about private files access

[pw44]

Hi all,
i do have a question regarding private files access:
when accessing the private files (media), i do need to give in the pin. Ok. But when, trying to access another file, i do need again to give the pin. Is there a way that the access to private files have a timeout, i.e. 10 minutes, before asking for the pin again? Or selecting the user, giving the pin, it's valid for a certain period of time...
TIA,
Paulo
