How do I create custom input field in my dialog triggers for my custom recognizer to read?

Question

I made a custom recognizer component that works fine and just as expected however it has one limitation I would like to overcome.

When creating your dialog triggers the default recognizers, which are LUIS and RegEx, have custom fields inside the composer.

For the RegEx the field is "Please input regEx pattern" and for the LUIS one the field is "Trigger phrases": https://imgur.com/a/AkfpjlB

I have found these two fields, "Please input regEx pattern" and "Trigger phrases", inside the source code of the Bot Framework Composer project however that is very unappealing way of going about it for me. I was wondering if there is a built in way to modify this "Create a trigger" window to have custom input fields like you can when creating your custom components in .schema files.
