I couldn't find any predefined structure type for tagged values, to be able to create a multiple choice list in Enterprise Architect. For example, in my projects, I want to have a tagged value which is a list of different product variants names. I want to choose for each requirement, which variants are relevant with this requirement, at the requirement elicitation and analysis stage. I could not find any way to create such multiple choice list as a tagged value.
For example, it should be looking like follows.

Thanks if anybody has clue if it is possible. I request Sparx to create such feature, if it is currently not available.
