Making the standalone instrument load an instrument by default

I would love for my standalone instance of Halion to load an S90ES piano by default, so I can have a one-click piano at the ready just by clicking the Halion icon on my taskbar. With a previous version of Halion I was able to have this, but now it does not seem to work since the update.
I have attempted to search for how to accomplish this but have not come up with a workable solution. Would anybody kindly be able to point me in the right direction?

Maybe this? A multi with just one patch?

Mine does not have this option:

It’s a context menu, right-click where @Geppastro has circled.

Thank you, that worked.
