zoom to selected set in Schematic editor

[vlsidesign]

In Virtuoso layout tool, you can zoom in to the selection
(leZoomToSelSet). Is there a comparable schematic editor command
function?

I am not on the new Cadence right now, so I needed your custom
function.
Thanks Andrew, it works beautifully!
