Django admin uninstall page acceleration

Question

How would you speed up the action / record of deleting a Django Admin entry?

I have model B with a foreign key constraint for model A. For each entry in A, there are about 10k entries in B linked to A. Therefore, when I need to delete an entry in A, using the default value "Delete Selected" "Actions in admin , Django will take 15 minutes to request and display each deleted record in B. How can I change this so that instead of listing thousands of dependent objects, only the number of dependent objects deleted will be displayed?
