I want to bind the sparklines history query time range to something just like how I can with the tag path but for some reason there's not a property for that. For example I want them to be able to change it from last 2 hours to last 1 hour etc... in the actual browser like you could with the regular chart component. Is this possible?

You click the little _`fx`_ icon under 'Most Recent' and enter an expression, such as a reference to another property, that will be fed in as the number of hours. You can't currently make the _units_ dynamic, but you can always choose the most granular unit you need and do the multiplication yourself.
