Class association roles

Question

For class associations multiplicity can be provided by -- "0..1"for example. This string field can be used for association role name alternatively. However, seperating the fields for both does not seem to be supported

Comments

Class assoications have distinct fields for association names and multiplicity, see object - Role name in association relationship - Stack Overflow so
