I have a subset of the following named ranges in several different
worksheets:

A_1, A_2, ..., A_20, B_1, B_2, ..., B_20, C_1, C_2, ..., C_20

Is there a way I can get a collection of those that are available for a
particular sheet using wildcards? For example, something like:

for each oRange in WorkSheets("XXX").Range("A_*")
....processing...
next oRange
