How to run scenarios in parallel wtih some sleep period between them?

Gatling (Open-Source)
1

Could you give me an advice, please. I need to make this case:
1step scenario1 and scenario2 should start in parallel.
2step: scensrio3 and scenario4 will start in parallel after 60 minutes when started simulations step1.
3step: scenarios from step1 must be stoped in 8 hours after started.
How can I develop a construction setup injection for Gatling?

We’r using free version Gatling3.3.1.

Have you checked the injection documentation? https://gatling.io/docs/gatling/reference/current/general/simulation_setup/#injection

Yes, I saw it.
I know how to start scenarios in parallel.
Like:
setUp (
scenario1.inject (rampUsers (1) .during (1))
.protocols (httpProtocol),
scenario2.inject (rampUsers (3) .during (1))
.protocols (httpProtocol),
scenario3.inject (rampUsers (1) .during (1))
.protocols (httpProtocol),
scenario4.inject (rampUsers (3) .during (1))
.protocols (httpProtocol)
)
But, here isn’t how start to the second group of scenarios (scenario3, scenario4) after Х minutes, after started the first group of scenarios (scenario1, scenario2) in this simulation?
If You point to a line of documentation, it will be so amazing.

Hi Elena,

See nothingFor (the first item of the Open model).

Cheers!
