Operator interface - Manual inspection - add sub unit - multiple allowed partrevs

In the add sub unit step of a manual inspection it is possible and practical to lock it to only be possible to add a unit of a specific part number and/or revision. This feature is limited to specifying only a single value for each field. The possibility to add multiple allowed part(rev)s would be highly useful.

Background for the request:

Certain of the PCBAs in our production has variants using different combinations of components and thus different part numbers. The different part numbers are important for production of the PCBAs, but for the final product these PCBAs can be used interchangeably.
