drop down from connected tool needs to be easier to implement

[mithily]

Maybe I am a newbie, but it is really galling that the drop down tool in the interface palette wont show the values in a connected tool unless they are spun up as headers in a cross tab using a record ID ruse. Alteryx really needs to provide this very common use case. This functionality is so easy to implement and is a fundamental part of any UI. Take a field and show its values as a drop down. Please tell me I am missing something and that this is really easy. I know we can save it as a name value pair in a yxdb and then input that, but I should not have to do so many things for what is an essential function.
