Question about MyAir app

[struts]

I mainly used SleepyHead, now OSCAR to check my sleep data. However, I don't mind using MyAir for very high level view of my AHI, mask air leak and usage hour. 

When I first registered, I was on trial machine from the CPAP supplier. After I returned the machine at the end of trial, I forgot to remove the machine in my account ( the app does not have option to remove machine anyway), and now my account has data from that trial machine by other users.
Is there any way to delete certain period of data in my MyAir account , without having to delete my account ?

Thanks.

You'll probably have to contact the supplier for assistance with the MyAir. Unless it has a reset button to remove the connected PAP machine data.
