Bluetooth two phones to car stereo

My work installed Microsoft Intune on my work phone, so I’m no longer able to access the Apple App Store. Additionally they removed the Apple calendar, access to outlook notes and tasks in the Apple notes and reminder applications. So now I’m forced to use my personal iPhone and link to the work exchange account to get those features. However, my biggest problem is I now no longer has access to Pandora or Podcasts on my work phone. My job requires to drive a lot so I need my work phone paired to my work truck Bluetooth for calls and MS Teams meetings. If I connect my personal phone to Bluetooth, I can still do all of this but I have to use my phone for work calls and I don’t people having my personal number.

Im trying to find a way to hook both phones through the Bluetooth system so I can still use my personal for podcast and pandora but my work for calls and meetings. I’ve looked at Bluetooth transmitters and receivers but they don’t appear to solve my problems. Any ideas?

PS. Don’t let your company but Intune on your phone, it sucks!
