Allow workflow input from multiple data tables
It would be very helpful if a workflow could take inputs from multiple data tables. Not all use cases are covered by the <x>, <x>_set model as the only table combinations in a single workflow, for example in the standard genomic data model where participant data is stored in one table and sample data is stored in another table. Another example is storing multi-sample VCF files in a table with one row per chromosome (as the "workspace data" table that only allows key/value pairs is not ideal for that).
Even if there could be only one primary data table (referenced by "this" in the workflow input selector) where outputs of the workflow are mapped, being able to reference other tables by name would be extremely useful.
