In Excel 2002 I can format a shape with a pattern. I can choose from 48
patterns in the list.
If those patterns aren't suitable is there any way that I can specify an
additional pattern?
eg Can I add some patterns programmatically when Excel starts up?

Here's what I do:
1) Add an AutoShape
2) Right click the AutoShape, choose Format Autoshape...
3) Choose Color dropdown
4) Select Fill Effects...
5) Choose Patterns tab
6) See 48 patterns, none of which are quite right

At this point I'd like some more patterns to be available. I'm happy to
write some VBA to get them in the list if possible.

cheers,
Jonathan
