Using neural DSP as fx send (in reaper)

I really like the reverb and delay effects in the archetype: Plini plugin. Could I use the plugin as a general reverb send for example so I can add the same reverb to all instruments in the project without having to use the plini plugin for all of them?

You could use plini on an effects bus with everything but the pedal section turned off. Send your tracks to the bus and you’re set. If you don’t want to bus those tracks together, using multiple instances of plini with the amp/cab disabled works.
