Allow users to enter a Twitter, Facebook or G+ URL to associate with a lead or contact

Currently, the only way to associate a contact's or lead's social media profile (Twitter, Facebook or G+) is to let Zoho CRM search for the person's name. However, that only pulls up a limited number of results, so it often doesn't pull up the right profile if the person's name is a common one..

Please allow users to enter a Twitter, Facebook or G+ URL for a lead or contact (in addition to the option to search). For example, in my situation, I am already Facebook friends with a person who I am adding to Zoho CRM, so I know the URL to his profile. However, his profile doesn't come up when his name is searched (other people with the same name come up).
