Perspective Horizontal Menu opening new tab instead of in existing

It’s probably more a feature request, but I have a horizontal menu with a tab targetted to another gateway’s Perspective project, but this link opens in a new tab instead of the existing one. I have a link to each other’s gateways from both projects so I don’t need a new tab. Guessing you can’t do this right now (in 8.1.5)? (with the standard props, but obviously can work around it)

Maybe with the onitemclicked event?

yeah that works if you set the target to nothing, and then use a script it will open in the current tab (but it will ask if you want to leave the site)
You’ll just have to add some if statment to it, so it will only do this script if the correct link is clicked
system.perspective.navigate(url = "")
