How to add property queueAtTop="true" to a Ant build?

I was using custom build of meter runner, which is from https://github.com/JetBrains/meta-runner-power-pack .

I was trying to make a build to the top of the build queue.

But I could not really do it with priority settings since the low priority tasks still could jump to the top.

I was wondering if I can add the build property queueAtTop="true" into the meter run script.

Thank you.
