As per siteini remarks:

3. For USA only, create a provider list by zipcode
*              Skip step 1 and 2 above,set the site_id="xxxxx" to desired zipcode,example 10001
*              <update>c3-10001</update>
*              <channel update="i" site="tvguide.com" site_id="10001" xmltv_id="dummy">dummy</channel>
*           4. Create a channel list for a provider from above steps,example zipcode 10001 dish network
*              <update>c4-10001-dish</update>
*              <channel update="i" site="tvguide.com" site_id="9100008443" xmltv_id="Dish Network New York">Dish Network New York</channel>

So i run <update>c3-32092</update>   and channel line 
<channel update="i" site="tvguide.com" site_id="32092" xmltv_id="dummy">dummy</channel>

as result of the wg++ run i get tvguide.com.channels.32092.xml

i choose provider i want (i.e Dish Network Jacksonville) then  run 
<update>c4-Dish Network Jacksonville</update>  and channel line 
 
    <channel update="i" site="tvguide.com" site_id="9100006458" xmltv_id="Dish Network Jacksonville">Dish Network Jacksonville</channel>

As result I will get tvguide.com.channels.Dish Network Jacksonville.xml   this is the final channel list, select channels, set update f  and run wg++
