Tasks by Planner - customize template

I'm just wondering if we can customize the template in creating task in Tasks by Planner and To Do in MS Teams?

For instance, we want to add an additional custom fields on it or we want to show the auto-generated reference# of each task?

Also, is there a way to retain the last filter applied? for instance tasks assigned to me? so that I don't need to click on it every time i access the planner

Also, is there a way to retain the last filter applied? for instance tasks assigned to me? so that I don't need to click on it every time I access the planner. Basically, team members will see the task assigned to them by default but have the flexibility to change filter while manager can see all tasks.
