Special Chords without 3rds

Hello, I bet with all the possibilities in Hooktheory’s chord choice, you were not expecting this question.
I write chords without the major 3rds and minor 3rds.
For instance I like CDG which is a C9th without the 3rd.
CFG would be a C sus4rth.
No thirds…
How should I use Hooktheory to have chords like these?

Hi Terry,

in the chord menu at the right side you can find a “no3” option. I think this should do what you’re asking for.
