Dynamically prefill field values

Good evening,
I was googling but unfortunately did not find a working solution. So I would like to ask you if it is possible to prefill some field values by php shortcodes (like this one: [php function=3]).

e.g.:
– to prefill default text of field by shortcode
– to prefill redex value by shortcode

With kind regards… S.
