Multiple custom post types under one admin menu

Using CPT UI I created 3 custom post types: test and test_1 and test_2.
I published posts under test_1 and test_2.
In test_1 and test_2, I set “Show in Menu” to True, and the top level admin page to edit.php?post_type=test. This effectively puts test_1 and test_2 under the top level admin page of test.
Now, is it possible to list all the posts under test_1 and test_2 when I click on the top level test post type in the admin menu? In other words, when I navigate to /wp-admin/edit.php?post_type=test, I would like to see all the posts from test_1 and test_2.
Thank you
