Changing scales within a progression

This might be a stupid question but how can i change a scale within a progression? Keylock seems locked to one scale or chords but if you change from one scale to another I don’t see that there is a way to change it?

Just curious, what is changing a scale within a chord progression supposed to do? It wouldn’t alter the chord’s composition, it’d still be the same notes, no? Are you thinking about “changing key” like in a DAW?
