Filtering Keynote Schedule by Prefix

[Limbatus]

Hello,
i'm trying to sort a keynote schedule by keynote prefix so that it would read like this

1.01
1.02
1.03

2.01
2.02
2.03

3.01
3.02
3.03

when i attempt to filter, it works for my first set 1.00s, but omits my 2.00s, and 3.00s. Is there any expression i can type in this field to get this working correctly?

Sorry, no can do. You only have the options to sort by the number as a whole. No way to sort using only Leading Characters (like you can for the Browser Organization)
