No such thing. The Helix replicates the studio sound, more than anything. When mixing, reverb is added post the amp/cab. The exception is the '63 reverb unit, when it was placed before the entire amp/cabinet. You can, however add the reverb before the cabinet, if you use separate amp and cab blocks. Honestly, it's all cork sniffing, and with some tweaking you can always get your desired sound. For example, you can experiment with adding a compressor + reverb between the amp and the cab.

Not that I know of. It has been requested before. Best you could do is do a pre or full amp without cab -> reverb -> cab.
