Copy/Paste to Create Composites
If you have the Professional Edition, Complete Composites can be used to create many composites, for example to create subscripts from superscripts. However, if the glyphs are not mapped, for example, if you want to create denominators in the Private Use Area from superscripts, or if you're using the Home Edition, then Complete Composites won't be an option.
However, composite glyphs can be created by selecting the glyph members in the glyph overview, copying them to the clipboard, then pasting them into the empty glyph where you wish to create the composite glyph.
To speed up the process of creating all ten denominators from the ten superscripts, copy them all at once, paste them all into the target glyph, then delete those you don't need.
Select all ten superscript glyphs in the glyph overview using Shift + Click, and Ctrl + Click. They will probably be in the order: 2,3,1,0,4,6,7,8,9 if the font is sorted in the standard order.
Insert ten empty glyphs at the end of the font. Denominators intended for use with OpenType Features don't need to be mapped. Or, you can map them to code-points in the Private Use Area.
Open the first empty glyph and paste the ten superscripts from the clipboard. You will see a confused mess of glyphs like this:
To select the superscript zero cycle through the composite glyph members using the "w" shortcut key — the zero, which is the fourth on the clipboard will be selected with three presses of the shortcut key. Holding shift, press the down cursor about five times to separate the selected glyph from the group. If you get the wrong one at first, try again until the target glyph is separated from the group and in the right position on the baseline like this:
Use the shortcut key "Ctrl T" to invert the selection to get this:
Press the delete key to delete the selected glyphs, and use the shortcut Alt Right cursor to move to the next glyph. Paste the clipboard contents again (Ctrl V), and repeat the process for the next denominator.
Using composites instead of simple glyphs reduces the size of the TrueType font file and makes the font easier to edit. If you later decide that the superscripts need to be bolder, for example, you only need to edit the superscripts, for the subscripts and denominators to be updated too.

Reason: Shortcuts for Previous/Next Glyph are Alt Left/Right
