Ability to store short versions of eligibility criteria

During a private USDM training (large pharma company), it was indicated that eligibility criteria are often shortened for submission purposes (for example for SDTM and/or ClinicalTrials.gov).
The question arose of how to store these shorter versions and whether it would be an option to add another attribute to the eligibilityCriterion class pointing to a shorter text description in the eligibilityCriterionItem class.
In that case, it might also be helpful to be able to reference and or group eligibility criterion items.
