In a conversation with support earlier this week, I was told a modifiable duration was coming in an update soon. They had no further details such as would it be in a drop down list of pre-determined values or input manually. I was trying to get a 3 second duration for a specific function. I learned in raw mode successfully once only, the rest of the time I got errors during the learn. Support said right now it's difficult and they expect the duration function to help.
