Joining WIth Hyphen

[Wayne_Wickson]

In three of these examples, there are two names composed completely of capital letters. I need to format only these two names in capitals with only a hyphen between them leaving the rest of each filename unchanged. The routine should leave the fourth example untouched, as the second name is not composed entirely of capital letters.

With a checkmark for "Inc.Ext.", the "Match" and "Replace" can be like...
^(20\d\d_\d\d_\d\d [A-Z]{2,}) ([A-Z]{2,} .+)\.(?i)jpe?g
\1-\2

This one was a winner too, Luuk! Thanks so much for taking the time to do this.
