To change extruder it needs Both extruders to heat up at the same time!

Hey Guys,

 

I have a Raise3d Pro2 printer -

I did a print with the Right extruder and when I finished I wanted to do a new print with the Left extruder.

But, I noticed that the left extruder won't drop down unless the right extruder heats up as well (which makes sense).
The problem is that both extruders don't always heat up at the beginning and I don't understand why?

 

I have to manually go to the Utility screen, heat both extruders, and drop down the one I need.

 

Is it possible make both extruders to heat up at the beginning and then drop the Temperature for the one I'm not using? 

 

Thanks.
