PDS .drv file, how it is created/modified?

Hello everyone,

Can someone explain me how .drv file is created in PDS (I know that it is created via Design Review Integrator)?
I want to know which references are drawn from the database to create .drv file. As you can see in the screenshoot example of the drv file... Screenshot
When we integrate the piping model in the NavisWorks it doesn't show the KKS number (It shows branches) beacuse the ":" mark in NAvis is the divider for data.

So is it possible to turn off the "LTG:" text and move it up on the acctually KKS number?

Wee have looked at the labels module but haven't found anything relevant to this...
Thank you all! Any help is appreciated
