If I needed two loading coils for one antenna to cover LF es MF I think I would use one Loading coil and short out turns not required for MF and one Variometer would do both.
I do not have a loading coil on MF because the antenna is a full size 1/4 wave inv L for MF and a separate antenna system for LF with around 400 uH loading/matching coil, no variometer, turns tapped up/down for a 50 ohm match.
