Use `company-auctex` with `company-dabbrev-code`?

[MarcinCiura]

Thank you for your work on company-auctex.
Besides predefined macros, I have a .tex file with lots of private macro definitions.
Would it be possible to use company-auctex's macro-finding logic and plug it into company-dabbrev-code to get auto-completion of private macros, too?
