I have a popup that I've linked to a create button in an LOV, using the "createPopupId" property on an inputListOfValues element. This works great, except that it seems to align the popup with the create button in the LOV. (highlighted in yellow is the "Create Icon" that's calling my popup) instead of in the middle of the screen, or aligned to another arbitrary component of my choosing:

I found a lot of useful info on how to set the popup alignment programmatically via popup hints, and if this was a manually-created action I think I'd be good. However, since this action is instantiated by the auto-created create button in the LOV component, I'm not sure if/where I can intercept the action that launches the popup to inject the alignment hints?
