Sort "Link to Item" Column

At the moment, when you sort a “Link to Item” column, it seems to sort it by the first tagged item in that list.

We have a board for all of our customers that is auto populated by the API.

We have a second board for feature requests, and on the feature requests board, we have a “Link to item” column that allows us to select a customer from the customers board.

We would like to be able to sort that column by the number of linked items. This way we can see our most requested featurs.

At the moment, when there are more than 2 items, they do group into numerical values. E.g. 12 items, 30 items etc. Is there a way that this could be sorted so the items with the most linked items are at the top?
