Possible to use one OTA channel's guide data for another's?

In Los Angeles, there are ATSC 3.0 channels currently getting broadcast on different channels than their ATSC 1.0 counterparts. For example, Fox has their ATSC 1.0 channel on 11.1 and ATSC 3.0 channel on 111.1. Right now, channel 111.1 doesn't have any guide data. Is it possible to configure Channels to use the 11.1 guide data for 111.1? Even better would be to be able to disable the current channel 11.1 and have it instead use 111.1. Thanks!

Click the gear icon next to your HDHR on the DVR web UI and select Sync Mapping

You can also make custom channels that will force the use of the 3.0 transmitter.
Here is an example that I used to stop the HDHR from using the translators.

You have to manually map them, do this:

Also, if you only want the ATSC 3.0 stations, then just favorite those ones and hide the ATSC 1.0 ones. Or use a Channel Collection to decide what you want to see in your lineup and in what order:

There is no need to hack or do anything special; just use the built-in tools!
