WPI Lib Relay class - individual line control

[de_]

I can't quite figure out the WPI Lib description as to whether we can individually control each of the 2 output lines without effecting the other line. Here's an extreme example

On one line have an (12v) Red LED connected and be able to turn it on and off without effecting the state of what is on the other line of the spike. On the other line, we want to have a white 12v led that we flash in software, again, not effecting the Red LED.

The class description seems to hint that we need to declare 2 relays on the SAME channel,
- one with forward only (line 1) control
Relay m_relay1(1, Relay::KForwardOnly);
- and one with reverse only (line 2).
Relay m_relay2(1, RElay::kReverseOnly);

And then we can control each line relay individually.

Or do you declare a single relay and change the direction to access a specific line on the fly like

Relay m_relay(1);

:
m_relay.SetDirection(Relay::kForwardOnly); // access 1 line of the spike
m_relay.Set(Relay::kOn) ; // set On or Off 1st line
m_relay.SetDirection(Relay::kReverseOnly); // access 2nd line
m_relay.Set(Relay::kOn); // set On or Off 2nd line....

Sorry last coding I did was on an RC
