How to assign value from a struct to a bus

Hi

I've got a complex struct with different values in Matlab (a car with different components and for each of the a lot of parameters as MTTR, MTTI ecc), i generate a bus with the exact same form (i generated it form the structure, so it's exactly the same).

When i generate an entity in simulink (the entity rappresent my car) i choose "bus" as "Entity" type and i assign the bus i created as "Entity type name".

My problem now is that the entity is rappresented by the bus but there aren't value in the bus and i need to copy all this value from the struct in Matlab.

There is a way (a block or so) to automatically import all the numbers contained in the struct?

for example ai have:

car.door.MTTR=50;

when i generate the bus the value 50 is lost, so in simulink i need to reasign it

many thanks
