Yes, with ?args=

You're familiar with using -exec #2 to launch the second module from the autolaunch menu of a local package.  You can do the same with Cameyo Online, e.g. https://online.cameyo.com/apps/636612078532635533/play?args=-exec%20%232

You can also use just the executable from the package, e.g. https://online.cameyo.com/apps/635145205139877083/play?args=-exec%20scalc.exe

You could do away with the second module in your particular package and use your -offline command in the URL, i.e. https://online.cameyo.com/apps/636612078532635533/play?args=-offline
