Editing Project for Web Tasks in the New Planner

I have a Project on P4W with custom fields that I created with Plan 5. I can see the Project Tasks assigned to me under "My Tasks" in the new MS Teams Planner but the tasks don't have any of the custom fields and I can only close the tasks. 

When I go into the Task and it says that the Tasks was created in a premium plan.

When I hit the "Go to premium plan" link, it brings up the P4W project in planner.

Can Planner be able to display custom the custom fields in a Tasks and allow updates to these fields or other fields underneath the "My Tasks" category? Also, would other users without a Project or Planner Premium license be able to do the same?

Regards,
