Can you change ExecWait detail text?

I'm working on an installer that during the install executes another installer the command I use to do this is:

ExecWait '"msiexec" \i "$INSTDTIR\povwin.msi"'

But I would prefer the installer says: Launching POV-Ray installer...

Rather than: Execute: "msiexec" \i "C:\path\to\install\povwin.msi"

It's no big deal but the default is a bit ugly. 🙁

It's all in the manual:

Thanks! I was able to change it.
