Can different Sessions be applied to multiple time frames

[mefTrader]

If my core strategy is running on say the Russell (TF) RTH (Session) can my 15min and 60min strategies run on "Default 24/7" Sessions?

How can I distinguish this?

Or if all 3 are running on Default 24/7 - how can I tell my 5min strategy which is calling custom indicators to only calculate on the Russell RTH Session...???

Using

protected override void Initialize()
{
CalculateOnBarClose = true;
Add(PeriodType.Minute, 15);
Add(PeriodType.Minute, 60);
etc. etc.

protected override void OnBarUpdate()
{
if (BarsInProgress == 0)
{
etc. etc.

mefTrader, this is unfortunately not possible - the primary series session template would be used when you Add() series programmatically.
