Radius update reply attrib

Hi!

After many tests, im here for confirm that, here is the question:

Does any attribute ,in Mikrotik implementation, exists that if i change it in a update reply and the Mk preserves changed on accounting requests?

I mean: Access-request came
Calling-Station-Id = “84:B5:41:B7:88:77”
User-Name = “Username”
MT-Realm = 0x123456

Can i send and update reply response with User-Name = “New_Username” or MT-Realm = 0x654321 and In IP>Hotspot on MK i could see these changes ?
Thus that accounting responses will be with the new attributes


Thanks
