I see. Actually I made a Resource because I tought that things like those you propose could be customized by using multiple resources, instead of a single one with many many options. I tought it would have been more manageable to do so. At least, this is the use I intended to do in my projecta. But I'll definitely take into consideration your proposal. Thanks again for your precious feedback!
