No, adding the space before the fleet number is purely to get the fleets to sort in the correct sequence when you want them sorted by Name . Currently the game sorts the fleets as '1st ..', '10th ..', '11th ..', '12th ..', '2nd ..', '20th ..','3rd ..', etc., as it's sorting on the first alphanumeric ...

In the meantime, rename fleets 1 through 9 by adding a space before the number, ie., change "1st Fleet" to " 1st Fleet". They will then sort ahead of fleets numbered 10 and upwards.
