Picking PHP Version for Crontab Scripts

I've installed the latest version of the PHP Picker app on my clearOS 7.4 box. The server is hosting a web app that was written in Laravel. The web app has components that require PHP 7. Of those are some crontab scripts.

I know that the default PHP in clearOS is version 5.4 and am wondering how to pick PHP 7 for the crontabs?

Here is an example of the crontabs I want to run:
0 2 * * * php /var/www/virtual/lms.domain.com/artisan draft-clear:document > /var/log/lms/drafts_docs_cleaner.log

Thank you.
