Did the sturmtruppen have a Headquarters or specific place to train?

Did the sturmtruppen have a headquarters or a main place for them to train or tryout? I've been wondering about this for around fourteen hours and can't find any evidence or information about it. If you have any knowledge about this, reply bitte.

Each battalion had its own "garrison" with quarters and training grounds etc. To give just one example: Sturm-Bataillon 4 (4. Armee) was located in and around Oudenaarde.
