Specifying From/ToRole and exact Cardinality in IMetadataProvider

Is it possible to specify FromRole and ToRole strings and exact cardinality for both ends of an association using IMetadataProvider?

The following code works for defining a new association sets with both ends. The cardinality is automatically selected based on the property's kind between values "0..1" and "*".

The issue is I have no way to specify a cardinality of "1" or "1..*". Neither can I find a way to set the association's ToRole and FromRole, as well as other association info like the Cascade Delete flag.

...

// Add navigation properties on both ends
// This end
ResourcePropertyKind propertyKind = associatedCardinality == Cardinality.ExactlyOne || associatedCardinality == Cardinality.ZeroOne ?
ResourcePropertyKind.ResourceReference :   
ResourcePropertyKind.ResourceSetReference;
ResourceProperty property = new ResourceProperty(propertyName, propertyKind, associatedType);
property.CanReflectOnInstanceTypeProperty = false;
resourceType.AddProperty(property);

// Other/associated end
ResourcePropertyKind asssociatedPropertyKind = cardinality == Cardinality.ExactlyOne || cardinality == Cardinality.ZeroOne ?
ResourcePropertyKind.ResourceReference :
ResourcePropertyKind.ResourceSetReference;
ResourceProperty associatedProperty = new ResourceProperty(associatedPropertyName, asssociatedPropertyKind, resourceType);
associatedProperty.CanReflectOnInstanceTypeProperty = false;
associatedType.AddProperty(associatedProperty);

// Create Resource artifacts
ResourceAssociationSetEnd associationSetEnd1 = new ResourceAssociationSetEnd(resourceSet, resourceType, property);
ResourceAssociationSetEnd associationSetEnd2 = new ResourceAssociationSetEnd(associatedSet, associatedType, associatedProperty);
ResourceAssociationSet resourceAssociationSet = new ResourceAssociationSet(associationName, associationSetEnd1, associationSetEnd2);
