Upvoting this idea and suprised it hasn't gained more traction yet! The "My Team" section in Hubspot Academy is helpful to see what your team has completed, but it would be so much more useful if you could assign or recommend specific lessons/certifications to your team.
While the referenced workaround is also a good suggestion, unfortunately it doesn't work if your Sales or Service team members don't have Marketing access in your account, as Hubspot Project Tasks may only be assigned to those users that have Marketing access. It's also pretty tedious to have to copy and past the links and build the Tasks.
