Is there a way to select which tuner to set the channel listing by?

[TechBill]

I have 2 different provider which I get my programming from and lots of the channel network on both provider are the same so SageTV merge any similar channel network together on channel listing which is fine and make it easier to maintain for me.

But my question is that even with both providers have the same channel network but different channel number, how does SageTV determine which provider channel number to use on the channel listing when it merge them together.

It seem to be that it randomly choose either provider channel number when SageTV merges it together and I wanted to just keep it all on the same one provider's channel number so is there a way to tell SageTV to use this provider's or tuner's channel number listing for all the channel it merges into?

Thanks
