Can Sketch or InVision prototype interactive forms?

I have used Axure RP frequently but there's a lot of companies who use Sketch + InVision for their design and prototyping.

However, as far as I'm aware there is no ability to create interactive form elements in InVision? (such as drop down lists, free text input fields etc).

If you want to prototype and remote user test anything with a form, i would think this would be pretty much impossible, as in remote testing it's hard to get the "it's only a prototype" thing across and you would want the user test to be realistic.

Just wondered if anyone knew if this was possible?
