Co Authors or Group Sharing or Multi Users

Hello,

This is my last question ever. If I could solve this, then the website will be finished!

On my website, there is a custom profile page, there are 2 sections ‘My Personal Profile’ and ‘My Directory Profile’.

Personal Profile shows logged in users personal details.
Directory Profile shows logged in user’s work place detail.

For example, Tom and John work at the same cafe, both Tom and John sees the same cafe details on My Directory Profile.

I read some of support forum, and I understand 1 listing per 1 author.
is there any way to show the same listing info on same group members?

So far I thought;
1. Use ‘Co-Authors Plus’ plugin, add co-authors (I installed this plugin, but I only see a listing on top author’s profile page, not co-authors)

2. Somehow share listing info between Group members

3. Somehow adding multiple users functionality on back end

4. Use ‘Claim Listings’ (not purchased yet) and claim ownership as group somehow

I’d appreciate if you could give me some advice, my PHP skill is limited, so I posted the same topic on job page. However I wanted to know if this possible with customisation? or really impossible task? If you could give me the direction, then I could write more specific description on job page.

Thank you so much for your help in advance.

Kind Regards,
Eri
