Tvheadend

Last night the local tv cable provider decided to completely re-arrange channels and implement some new muxes. Thanks to a decoder with OpenPLI and with the help of dreamboxedit I got the new frequencies which I just added to Tvheadend.

Now the problem, there are a whole lot of mapped channels, channels that are configured to the wrong/old mux, which results in "service instance is bad, reason: No input detected".

Is there any way of getting Tvheadend to update the muxes automatically or do I have to go change the mux of each channel by hand?
