Linking Subpanel from Contacts to Accounts table

Hi

I have a small issue I cannot figure out how to implement. And I did not find it anywhere so far.

In short words, I need to add new subpanel for Accounts module and display there some objects linked to the Contacts of this Account.

In long words here is what I have:

  1. I have a custom module describing Conferences that we attended
  2. I have this module linked to a Contacts module. (many to many relationship)
    So, a SuiteCRM user can specify that we have met some Contact at some particular Conference(s).
    (which gives us a possibility to see which persons we met at particular conference and see which conferences we met this person at)

Here is what I wish to add more:

  1. I want to add a new subpanel to Accounts module, so that if a SuiteCRM user selects some Account, this new subpanel would display the list like “a person from this account - a conference where we met this person”.

I need this as we meet someone from this Account at one Conference, and another person - at other Conference, and we need to have every Conference at one place linked to this Account.

I have SQL that can give me this list, but I cannot create this new subpanel - as I understand new subpanel needs new relationship, but all relationships are on their place. No need to create one.

Any hint on how I can do it?
Thanks in advance!
