Is it possible to show a list of siblings?

[olgaloza]

For example, on a Contact page we want to show a list all Contacts that are linked to its parent Account.

For that we would need to query for current Contact's parent AccountId field in the Filter, correct? I tried AccountId = #ParentRecordID.AccountId# and some other similar variations but the Filter field doesn't seem to take the variables/replacements like #ParentRecordID#.

Is the deeper tree navigation possible?
