Tvheadend

Hi, I wanted to ask, I have a m3u8 sheet, where there are several links to IPTV streams. But these links to those streams are changing, but always on the same programs. Every 24 hours the shape changes to the given stream. The link to the stream is always the same.

see
http://sdfsdfsdfsdf.cc/asdasdasdasd/75-tv-pc.m3u8
http://sdfsdfsdfsdf.cc/asdasdasdasd/47-tv-pc.m3u8
etc..

can somehow set the tvheadend to just refreshnul links, but preserved services etc ??? Nowadays I have to connect to the tvheadend server everyday and manually browse new muxy and add services and set up in channel ...
