Report Subscriptions allow Multi-value list of Input Parameters

I would like to submit the IDEA for an Enhancement to Astra Schedule that Report Subscriptions > Default Report Parameters would be able to take a list of values as inputs for a report run like array syntax.

Currently, Subscriptions' only allow single values for report parameters and I have already opened a support case to confirm if there was special syntax for a list of values to be used for an input parameter.  

I have already worked out the syntax of hardcoding values into a report, but really that is not a good solution for parameter values that are not long-term constants within an institution.
