Merge Two Radios Using ARC500PRO

I have two scanners for which I use ARC500PRO for each. Each currently has a different trunk and talkgroups. I want to merge both radios into one which would give me two trunks and the new talkgroups all on one radio. Both trunks have custom bandplans.



After looking around, is there an easy way to do this?



I looked at the CSV export and import but it does not seem to export the custom bandplans.
