Multi-Select filter option for non-picklist fields

In the new Superbank release, there’s now the option to add a multi-select filter to a table. This is great but only seems to allow picklist fields to be used. We really need to be able to use fields like “OwnerId” (for multiple user filtering) and “RecordTypeId” (for multiple record type filtering). Could we not provide a model for the selectable options like we can currently with a regular “select option” filter?

It would also be great if the new automatic condition table filtering could use non-picklist fields.
