@brassmonkey001, unfortunately you'd have to manually switch modes, as different modes for individual legs is not supported; that being said, however, whether you actually need to switch modes depends on your LFP bank manufacturer's recommended charge profile, as many LFP banks are perfectly happy at an FLA charge profile. Battle Borns, for instance, are totally content to charge at 14.4v, which should be the setting for FLA anyway. Just make sure you don't run equalization with the LFP bank connected!
I always defer to the manufacturer's recommended charge profile, of course, so be sure to check that... but it's very likely you'll find that your LFP and FLA banks have very similar recommended charge profiles. The LFP won't require an absorption cycle, but most of them will take it and be happy with it.
