Currently, in Indesign in german language "st" is always hyphenated. In my work, however, there are many compound words in which the "st" is at the beginning or end of the word and therefore the hyphenation of a compounded word must occur before or after the "st" instead of between "s" and "t".

Example:
"Führerstand", compunded of the words "Führer" and "Stand"

Expected hyphenation:
Führer-stand

Wrong InDesign hyphenation:
Führers-tand
