Device Assignment Constraints

We know that an employee can have multiple devices assigned to them (not common but still possible).

And the device types are,
i) Regular laptop
ii) High performance laptop
iii) Surface Pro 7
iv) Surface Pro 8

Based on the above information, I want to clarify
Can an employee have multiple devices of the same device type? Like can employee B have 2 regular 14" laptops?
Can employee C have one regular 14" laptop and one high performance laptop?

Also,
can add this constraint
“Of note... only CISB Community Integration Specialists receive Surface Pro's.
only included (union members) ABI folks receive High Performance laptops. “

Accordingly, can add further constraints in the database

Furthermore, only people that already have a mobile phone can request for a tablet. Maybe, this is covered by the previous constraint since only CISB folks have iPads and they do receive iPhones as part of their welcome package
