Hi - well, apologies first; not wanting to hijack your thread… Try this only if you get time/feel inclined… 
In which case, I think you should be fine - saving/loading channel settings (as ‘split’ mentions) should work ok; certainly with my example, when performing this across different projects… 
And to be clear/complete, I cannot check right now whether save/load channel settings is fully working correctly, when doing so within the same project… (The ‘sidechain’ compressor issue is only one instance/example, of that save/load process, which doesn’t work within the same project…)
