sync and News-APP

I use the News-APP in
My stored RSS feed generates news several times an hour. However, the News-APP updates this feed at a very large distance.
Only the administrator can change the synchronization distance.
I would be satisfied with a six-hour synchronization, e. g. 8 a. m. , 2 p. m. and 8 p. m.
Therefore my question to the administrator of Would this be possible ?
