replace underscores with hyphens on one parameter only and then 301 in htaccess

I am trying to replace underscores with hyphens only on a particular parameter and then perform a 301 redirect. I have figured out how to replace them and apply it to the entire URL but cannot figure out how to replace them for just one paramater. Right now I have this:

RewriteCond %{QUERY_STRING} ^state=([a-zA-Z_]+)&city=([a-zA-Z_]+)$
RewriteRule city.html /find/this/in/%2/%1/? [L,R=301]

This 301 redirects this: mysite.com/city.html?state=va&city=dunn_loring

To this: mysite.com/find/this/in/dunn_loring/va/

I would like it to instead 301 redirect to this: mysite.com/find/this/in/dunn-loring/va/

Essentially I only want to replace underscores with hyphens for the '%1' portion in my htaccess example above. Thanks in advance for any pointers

The below solution works with no limit on the number on underscores. The first RewriteRule replaces the first underscore seen and the [N] flag causes processing to start over, so the rule will keep being applied until all the underscores are replaced. When no more underscores are left, the redirect is issued.

RewriteCond %{QUERY_STRING} ^state=([a-zA-Z_]+)&city=([a-zA-Z-]+)_([a-zA-Z_-]+)$
RewriteRule city.html /city.html?state=%1&city=%2-%3 [N]

RewriteCond %{QUERY_STRING} ^state=([a-zA-Z_]+)&city=([a-zA-Z-]+)$
RewriteRule city.html /find/this/in/%2/%1/? [L,R=301]
