You have the opportunity to train five picking fingers, all of the fingers in your strumming hand. Don't waste the opportunity. But perhaps your little finger will only be needed in emergencies.
Training variations:
four vertical strings = one string for each finger, adding in the little finger enough to keep it awake.
four horizontal frets = one fret for each finger, adding in the little finger enough to keep it awake
four (or five) notes in a run in a scale = one note for each finger
four (or five notes) in a scale, but thirds or fifths = one note for each finger
anchor the index finger and use the others to play the scale.
all notes in a scale, a single line melody is an arrangement of notes in a scale = play the tune using all fingers sequentially, ignore how it sounds for the exercise
horizontal scale along one string
vertical scale over several strings
You are mostly going to use 4 fingers to pick the notes. That gives 16 combinations. Spend some excel time writing out the 16 combinations, then back to the fretboard and work through them. I think there are going to be one or two that are not physically possible.
The above are mechanical exercises like a runner doing weight training.
Now look at the scale musically. The first mode or major scale is the Ionian mode. The third is Phrygian, the fifth is Myxolodian, the seventh is Locrian. These are the notes that can used to make chords in the scale. Learn to pick these modes. Arpeggiate the first, third, fifth and seventh modes in sequence to arpeggiate the diatonic chord sequence. Pick a (simple to start with) tune, and use the melody as the first mode and arpeggiate in the 3rd, 5th and 7th for each note.
Look at other musical things of interest and move them into your picking activities, using all available fingers in various patterns.
When you want a break from playing and want to use excel, use ABC notation to do some composition, so instead of producing another fretboard map, create some melodies which make your fingers go to all the notes in the scales on the fretboard, and which can be made to sound pleasing. Add a lyric if it pops into your brain. If you can assign an audible note to a letter in excel, you might get it play back the tune. So you are not just using excel for mechanical stuff, you add some value and get it to help think about and create music.
