I think ... /%d/%1u/%1.1u/%n ... should work.

>From docs/variables.txt :-

You can take a substring of the variable by giving optional offset
followed by '.' and width after the '%' character. For example %2u gives
first two characters of the username. %2.1u gives third character of the
username. If offset points outside the value, empty string is returned.

So by my reading, "%1u" is the same as "%0.1u", "%2u" is "%0.2u" and you
want "%1.1u"!

Best Wishes,
Chris
