Curtains control with HDL

A few days ago I installed the curtains controller from HDL, I had no problem with the installation or with the basic configuration, them go up, down and stop perfectly.
The questions are:
1) How can I setup a button to turn the shutter? The shutter rotate when the motor works in the direction opposite to the last movement for 2 seconds.
2) I can make a curtain opens, for example 40%, with the touch of one button? How do I configure this?
Better yet, I can control the shutter button with a level?
1. Yes, You can use Macros Delay(2000) in Programming Tab or Scritps Command .Set for activate channel and IR.SetTimeout for Delay
2. can not be done 
3. Yes, You can use Level Min = 0, Max = 2 and in Programming Tab send Value of Level in Send Token (Send to Driver Group Macros)
