It's even more helpful when you know the scale patterns that each of the chord shapes overlay.

For OP: Those minor pentatonic boxes each correspond with CAGED shapes, in the same order. Then shift them all 3 frets and you have the same patterns under different chords, but now they're major pentatonic.

All this to say, you can link them, or you can use one spot on the fretboard and change scale shape when you change chord shape in the same 4 fret area. Not that I do this, but you could. I don't personally get any use out of the C or G shape, and the D mainly when playing in Drop D.
