Zoom B3 question

I currently own the Zoom Multistomp MS-60B which sounds good but is awkward to use in a live situation. I'm considering the B3 but want to make sure it doesn't have the same issues.

As I understand it, on the Multistomp, you can't turn a patch (with multiple effects) off and on repeatedly. You can turn the individual effects off and on, but not the patch. Please correct me if I'm wrong.
The patches are assigned letters of the alphabet and you go through them in order. So to turn a reverb/chorus combination off and on you would for example make that patch be letter A, then dry (no effects) be B then the same reverb/chorus patch C and dry D and so on. At least that's how I understand it. I'd love to be wrong and save a couple of hundred bucks buying something else.

Questions:
1. On the B3, is it possible to set up a patch with multiple effects and use one switch to turn the patch (with both effects) off and on repeatedly?

2. Also, on the Multistomp it doesn't appear that the chorus effect is stereo even though the unit has stereo outs. At least I don't hear a significant difference. There is a patch called splitter that separates lows and highs but I don't see anything else. Am I missing something or is this a mono chorus?

3. Does the B3 have stereo chorus?

 

Thanks. I set up the bass to run stereo through two separate amps, it just didn't sound very different from the mono setting. In comparison, my Digitech unit (which just recently died) had a beautiful stereo chorus that was dramatically different.

The whole reason I got the Multistomp was to have a small footprint on stage. I mostly only use chorus, reverb, and delay so it seemed like the perfect solution. If I have to add another switch to either that or the B3 it defeats the purpose. Sounds like Zoom doesn't have the answer for me.

Does anyone know of any other effects units I should consider?
