Using a SEF URL component together with CB substitutions?

I am using CB substitutions to create a unique URL for members to use to pass data to a form. The substitution code I am using is below:

www.samplsite.org/index.php?option=com_chronoforms5&chronoform=SurveyForm&tmpl=component&coachnum= [user_id]&coachname=[cb:userdata field="name" /]&coachemail=[cb:userdata field="email" /]

I am using this code to display the unique URL in a field on the user's private profile page.

The problem with this is that it makes a very long URL and unfortunately I can't cut anything out because I need all of the data that is in it to be passed to the form.

Is it possible to shorten the URL that is displayed? Can I use a 3rd party SEF URL component (or even the built in Joomla SEF)? I would prefer to have something like

www.samplsite.org/index.php?coach=23

instead of the long and tedious:

www.samplsite.org/index.php?option=com_chronoforms5&chronoform=SurveyForm&tmpl=component&coachnum=23&coachname=JoeSmith&coachemail=joe@nowhere.com

Would a SEF URL component work for this or would it still display the long, unSEF'ed URL in that field in their profile? I figured it wouldn't work because of the way CB is creating the URL. Any insight or help would be gratefully appreciated.
