Spark - Extend CreateTeam function with more parameters

Hi,

I am struggling with being able top extend a function that is called when a new user registers with a team on a spark environment.

I am wanting to include a Team Slug field which the user has to complete on the main registration form before being able to register. I have successfully added the field to the db using a migration script, I have added the field to the view and have been able to extend the validation functionality which is cool.

I am now struggling with the function below as you can see the else statement hard codes what parameters to pass through, in this case, it is only passing the name:

Spark::interact(CreateTeam::class, [$user, ['name' => $request->team]]);

I would like a way to be able to extend or swap this function so it can accept my slug parameter, or a simple array of options:

Spark::interact(CreateTeam::class, [$user, ['name' => $request->team, 'slug' => $request->slug]]);

Here is the function I am wanting to swap:

/**
     * Attach the user to a team if an invitation exists, or create a new team.
     *
     * @param  RegisterRequest  $request
     * @param  \Illuminate\Contracts\Auth\Authenticatable  $user
     * @return void
     */
    protected function configureTeamForNewUser(RegisterRequest $request, $user)
    {
        if ($invitation = $request->invitation()) {
            Spark::interact(AddTeamMember::class, [$invitation->team, $user]);

            $invitation->delete();
        } else {
            Spark::interact(CreateTeam::class, [$user, ['name' => $request->team]]);
        }

        $user->currentTeam();
    }

Can anyone confirm if this is at all possible?

Thanks in advance
