Customizing captions

Hello,

how can I customize my captions (also for auto-captioning)?

Let me clarify:
now, the only format that I am able to use is " ", whereas I would like to use " "

i.e. instead “Picture 1.1” use “1.1 Picture”

Menu/LIbreOffice/Tools/LibreOffice Writer/Autocaption - Caption Order.
