How can I receive text messages from two phone numbers in one app?

[Android Central Question]

I have a Samsung Note 9, and service with AT&T. I have my regular cell number with AT&T (ATT), and I have an additional number with Google Voice (GV). I have the pre-installed "Messages" app on my phone and I have installed the Google "Voice" app. When I get a text message on my GV number, I have to look in my Voice app, but when I get a text message on my ATT number, I have to look in my messages app. I only want to have to look ONE place, at ONE app to see all of my text messages. Is there someway for me to see all of my text messages in one place?

Have GV forward your texts to your normal number (on the site - Google Voice under Messages > Forward messages to linked numbers). You'll have to disable handling texts in Hangouts (at the same site).
