Keep chord symbols aligned vertically, even if adjusted horizontally

When using a nonzero Maxmium shift above setting (Style → Chord Symbols → Positioning), each chord symbol is aligned vertically with the others in the system - unless its offset is manually adjusted in either X or Y.
This makes sense when I want to override Y manually, but I very often need to adjust the X, but want to keep the vertical alignment,
e.g. when many chords are close together in a measure, or to move out of the way of a volta number:

1. Without any manual adjustment - chords are aligned with the shifted F chord, but G pushes voltas even higher:
   
2. Moving G to the right breaks vertical alignment despite leaving Y untouched:
   
3. Desired end result:
   
   Achieving this currently requires eyeballing & manually adjusting Y, and will easily break again, e.g. if the high note in the 1st measure is changed.

(Tedious WA to determine the shifted Y position somewhat accurately:
Create another chord with the same letter as a reference. Drag original over it, and release mouse once they overlap as closely as possible. Reset X value to desired shift, keep the matched Y value. Copy Y value to any other horizontally adjusted chords in system...)
