Increment a number value within a string of varying lengths

I have a series of statements of varying lengths that contain a specific text and numeric value that I would like to increment. Using the Find/Replace function would take too long with the number of changes to make.

An example of the string to find is "Row-1", "Row-2", etc. and can be found within a larger string such as ".opStatement-indent .row-7 .column-1" or ".opStatement-rowcolor .row-20 .column-5".

What I would like to do is increment the "Row-" value by one. Because the row number can grow to over 100, doing a manual search and replace within this string became unbearable.
