Converter Redirect for Profile Pages

I recently moved my site from vb3 to IPB4 and all seems to be working well. VBSEO urls for topics are redirecting properly. Does anyone know how I could redirect member profile page urls to the new IPB url or rewrite it in FURL settings?

my urls are like this:

OLD: http://www.sitename.com/membername

NEW: http://www.sitename.com/profile/####-membername/

I either need to redirect or make the IPB urls same as old via htaccess or FURL settings. In FURL settings, I don't see where I can use Display name and since there is no ID in the old url, I'm not sure if I can achieve this.
