EPG Update Automatically

#1
Hi:
I entered in Settings => Options => Guide
A link to a XML guide and an alias.
If i press update everything syncs as channel names match, this works fine.

However the .xml file is generated/updated by a program every few hours. How can i do to force progdvb to read this without being needed to press the update button there?

I have the ProgDVB pro version 7.11 installed
