Shortcode for direct message link

Hi,

Is there a way to have a direct message link to the message to a specific user for example, like the same as below shortcode but with no button?

[bp_better_messages_pm_button text=”CONTACT US” subject=”Your Subject” message=”Your message” target=”_blank” class=”extra-class” fast_start=”1″ url_only=”1″ user_id=”1″]

Or else is there a way to pass it through a href link with specific user id?

Thanks!
