Multiple levels of query input

Hi, I had a use-case which I can describe as follows -

I have two queries A and B, where B depends on A (dropdown based on query provided by A).
Then I have another query C which is fed by B (for dropdown based on query).

What I would want is that I get two dropdowns, for A and B each. Then on selecting the correct input from A dropdown, the dropdown by B is populated, and then that is fed into C.

Is this is possible right now in some way? If not, any possible work-around to achieve this?

Thanks!

This is a pretty common request. It’s not supported right now and no workarounds that I’m aware of.
