Catchment Inflow (WET) collection

Hello,

I'm having following arrangement in my model.

CM 3 and CM1 is flowing to O2 and CM2 is assigned to O1 and simulated the model.

in the second scenario, I want to assign the the inflow time series of O2 to CM 2 as a Inflow (WET) collection.

my question is, in the Second scenario, does it count the time of concentration of catchment CM2 for the the flow time series assigned as Inflow (WET) collection to reach O1?
