Adding a contact from phone to a particular group

[Mity]

I have two accounts on my iPhone: Gmail and Outlook. I have my personal contacts in Gmail and my work contacts in Outlook. When I add a contact from recent calls, they go directly to my Gmail account (because Gmail is my default setting). I do not have Apple Contacts enabled. However, I want to be able to save a contact to a particular group directly from the phone, like Outlook for example. Is this possible?

The only way I am able to do this is by opening the Outlook email app and then adding contacts in there. However, that's inconvenient as I want to be able to add them directly from the phone to avoid copying and pasting.

Thanks
