syncing up the local and remote VFOs

I am part of a group of local and remote Flex radio users. We have 2 sites set up for complete RX and TX. The 3rd site is out in the country and used only for RX. (very low noise) We operate TX on the local flex while listening on the remote flex via smartlink. It would be really nice if the local flex slice (VFO) could sync up the remote flex so that with one control both slices would follow. This would save several clicks from local to remote to maintain the same frequency. Contesting is a chore this way. Has anybody figured out a way to do this. Node-Red gurus? Thanks for looking.
