Creating child momentary switch (without needingMomentary Button Tile)

I’ve got a SmartApp that creates a child virtual switch - a momentary type. Right now I’ve got it working just fine using the “Momentary Button Tile” type. However, I had forgotten that’s apparently not a built-in device handler - I had to go out and specifically install that in my environment. Has anyone figured out a way to get a simple virtual momentary device without needing this extra handler installed?

I see that if I go into My Devices and find the virtual “Momentary Button Tile” that was created, I can click on Edit, then change the Type dropdown to just “Momentary Capability” and everything still works great. What I really want to do is have the child device be that type from the beginning, but if I try to create a “Momentary Capability” child type, I get an error like “Device type ‘Momentary Capability’ in namespace ‘smartthings’ not found.”

Is there really no out-of-the-box way to create a momentary switch? It’s not a huge deal either way, but I’d prefer having one less custom handler that I need to ask people to install to use my app.
