The new Microsoft Planner: A unified experience bringing together to-dos, tasks, plans and projects

I have some feature requirements: Can Planner do the following:  

1. Client List - Maintain client profile - name, address, billing details, contact person, email ID, etc. 
2. Link each tasks to client, so that the team can easily identify the task to the relevant client, like how it can do so in people view. This will give a proper view to the management and operations that a "Task belongs to which client and who is the concerned person who is executing the task"
3. Attachments are presently limited to 10. This is hugely negative, we need no limits on the attachments. A secondary 365 folder, linked to the task page will also do, because each task will have a ton of files associated to it, which can be stored in the linked folder of the task.
