Support sort by count of collection field in Table View

For example, a database called A has a one-to-many field called B, there is 10 entity in the field.
Count of B will show in the Column button.
I want to sort by the number Count of B.

At the moment, the only solution is to create a formula field for this purpose.

This is a fabulous workaround.
Thanks.

Is there any plan to implement this? I am in fact using this as a very basic feature of feedback management: I have a table with the feedbacks as entities, and a column that counts the number of conversations with users supporting the feedback. I’d like to simply click the top of that column and be able to order the feedback based on the number of conversations, with the one with the most being at the top. This lets me see at a glance which feedback is getting the most activity.

Also relatedly I can’t seem to click the Public ID column and get the table to sort, while all the other columns seems clickable, I assume as of one of these releases discussed in this thread:

Am I missing the ability to click the Public ID column and have the table sort in ascending or descending order of the Public ID’s?
