Assertions that are scoped by Scenario?

I have a simulation that contains multiple scenarios. I would like to have different assertions for each scenario. Is this possible? The documentation shows group and request scoped assertions using the details method.

No, that’s not possible atm.
I don’t think it would be possible to implement in Gatling OSS without a huge effort as there are no per scenario stats there.

On the contrary, FrontLine does have those stats, so it would be possible to implement it there.
That’s not on the roadmap as of now, but if enough customers were to request it, we’ll take a stab at it.
