Deliver two independent stimuli at separate screen

[chiyu1203]

Dear Bonsai team

We would like to have two independent stimuli at separate screens so stimuli A only at monitor A and stimuli B only at monitor B
This should be a very straightforward question. For example, we can create two stimuli under the same PublishSubject module and set them at two different locations (BonVision website has a tutorial about this
However, we have a customized module where we can not change the location of stimuli (it was by default a module for full-screen stimulus where rots are moving toward one direction). Therefore I was thinking if there is any alternative way to achieve my request. I tried with using two PublishSubject modules and one connect to screen (see attached file) with its own sphere mapping but it does not seem to be working. It looks like one workflow will always overwrite the other one. So is there anyway to work around this issue? I think this is a having two independent Renderframe modules issue....does my guess make sense?
