How to generate superscript and subscript glyphs

There are 3 steps

=============================================================================
Step 1: Add Glyphs
-----------------------------------------------------------------------------

If these glyphs already exist, you can skip this step.

a=a.sups
b=b.sups
c=c.sups
d=d.sups
e=e.sups
f=f.sups
g=g.sups
h=h.sups
i=i.sups
j=j.sups
k=k.sups
l=l.sups
m=m.sups
n=n.sups
o=o.sups
p=p.sups
q=q.sups
r=r.sups
s=s.sups
t=t.sups
u=u.sups
v=v.sups
w=w.sups
x=x.sups
y=y.sups
z=z.sups
zero=zero.sups
one=one.sups
two=two.sups
three=three.sups
four=four.sups
five=five.sups
six=six.sups
seven=seven.sups
eight=eight.sups
nine=nine.sups
parenleft=parenleft.sups
parenright=parenright.sups
plus=plus.sups
minus=minus.sups
equal=equal.sups

Step 2: Generate & transform with RMX Scaler
-----------------------------------------------------------------------------

Make sure "Scale Sidebearings" is enabled in RMX Scaler.
Note that a-z(), 0-9 and +-= are scaled separately.

Start in the "Font" view in Glyphs (the tab with an overview of all glyphs)
and multiselect each set (e.g. "a-z()") then invoke the RMX Scaler.

-----------------------------------------------------------------------------
a-z, "(" and ")"

{
  "width" : [
    66.6,
    66.6,
    66.6,
    66.6,
    66.6,
    66.6
  ],
  "weight" : [
    0,
    0,
    -50,
    -50,
    -300,
    -300
  ],
  "height" : [
    66.6,
    66.6,
    66.6,
    66.6,
    66.6,
    66.6
  ],
  "verticalShift" : [
    1024,
    1024,
    1024,
    1024,
    1024,
    1024
  ]
}

-----------------------------------------------------------------------------
0-9

{
  "width" : [
    66.6,
    66.6,
    66.6,
    66.6,
    66.6,
    66.6
  ],
  "weight" : [
    0,
    0,
    -50,
    -50,
    -300,
    -300
  ],
  "height" : [
    60,
    60,
    60,
    60,
    60,
    60
  ],
  "verticalShift" : [
    1024,
    1024,
    1024,
    1024,
    1024,
    1024
  ]
}

-----------------------------------------------------------------------------
"+", "-" and "="

{
  "width" : [
    66.6,
    66.6,
    66.6,
    66.6,
    66.6,
    66.6
  ],
  "weight" : [
    0,
    0,
    -50,
    -50,
    -300,
    -300
  ],
  "height" : [
    63,
    63,
    63,
    63,
    63,
    63
  ],
  "verticalShift" : [
    1024,
    1024,
    1024,
    1024,
    1024,
    1024
  ]
}

Step 3: Adjust X offset for slanted glyphs
-----------------------------------------------------------------------------

For each slanted master:

1. Select all .subs glyphs
2. Open Filter > Transformations
3. Set Translate X = 126 (and all other values to neutral)
4. Apply
