I create my own custom .zwo workout files, as I prefer freeride mode over ERG. In order to know the power/cadence/HR target for each freeride interval, and what is coming up in the next interval, I use TextEvents that stay on screen during the entire interval. When importing a zwo. file into TPv these TextEvents disappear from the screen after a few seconds (while in Zwift they stay the predetermined duration).
Is there any command/tag in TPv to keep TextEvents on screen for a specific duration?

An example of a custom interval (in xml format), with a TextEvent lasting on screen the duration of the entire interval, would be as follows:

<FreeRide Duration="600" FlatRoad="0" show_avg="1">
<textevent timeoffset="0" message="Maintain 280W for 10min at 80-85rpm, next up 3min Recovery at 130W - Round 1/4" duration="600"/>
</FreeRide>

It seems TPv allows the timeoffset command, but ignore the duration command? As per TPv website, TextEvents code structure is:

!TextEvents:{
(timeoffset):(message);
}
