Simulink.Parameter with a nested struct

I was trying to set the data type of a Simulink.Parameter that contains nested structs using a bus object like so:

p=Simulink.Parameter;
p.Value=struct_params;
p.CoderInfo.storageClass='ExportedGlobal';
struct_params=p;
clear p;
busInfo=Simulink.Bus.createObject(struct_params.Value);
ParamType = eval(busInfo.busName);
struct_params.DataType='Bus: ParamType';
clear (busInfo.busName);
clear busInfo;

the problem is, that for the nested structs a bus type is created automaticly with the same name as the struct itself.

for example, a nested struct called subParams will get a bus type with the name subParams.

the c code can not manage a variable with a name that is the same as a data type.

(Like calling a variable uint32...)

is there a way to control the bus types of the inner structs?
