Hi guys,
I have the following request from our support team and i'm really struggling to find a solution, so i was hoping your help will be in use.
We have the following structure:
Customers have Accounts in our CRM, when they buy subscription from us (for a certain products) we store this information in custom entity called Subscriptions. The subscription goes with Order (payment confirmation), there can't be Subscription without order, they are always together.
Then for an account we can see all his subscriptions and Orders.
When you open the Subscription entity, you can see what is the order associated to it, which Account and Contact owns this Subscription.

Now the scenario:
When some of our customers opens a case with us, our support team must quickly see what subscriptions the person who open the case has.
In our Case form we store Account and Contact lookup fields.
As mentioned above, subscriptions are visible only on Account level.
This is how Case form looks like.

Now, i was thinking for a sub grid or Quick View form but neither one of them refers to Subscription entity and here we want somehow to get information for the related records only (in this case this is Account)
