KingBast - I think this is a better version of what we discussed. Rather than having to fudge some Tempcode symbol into the Comcode of some entry, you just write in a tag in a normal way. Then when adding the associated entry, you either put a main_multi_content block in the Comcode for that entry referencing the tag, or you do the same via a template.

E.g. you add some news about the band 'pentatonix' so you tag the news with that. Then when you add a catalogue entry for that band, you have your CATALOGUE_band_ENTRY_SCREEN.tpl template with something like {$BLOCK,block=main_multi_content,tag={FIELD_10}}. That's assume field #10 contains the tag version of the band's name.

Would be good for us to do a tutorial showing this.
