not disturb enable text messages

Hi!

Sorry if I posted this in the wrong place, I'm pretty new to apple forums.

Anyways, I was wondering if it was possible to enable text messages/imessages from particular contacts (or favorites, etc.) when do not disturb is active just like you can enable calls from favorites?  In case someone needs to contact you in an emergency but can't call for some reason.

And if not, are there any apps that could do this?

I want to be able to sleep at night, but if family has to text me in an emergency I would like to be woken up.

Thanks!
