You can't make a "real" custom autoshapes, but there are several
tricks to make pretty good substitutes. One is to create a Freeform
using using coordinates. You'll find enough info in the help help to
accomplish that. I've outlined a few other methods to create custom
autoshapes here:

If you want text capability you will end up having to make a composite
shape. For example, you can draw a freeform shape, place a textbox
over it, bring the textbox to front, set the textbox border to no
line, and set the textbox background to 100% transparency. Finally
group the shapes together and you have the effect of a custom
autoshape.
