[O] org-capture-templates - any way how to call function for template?

[David Belohrad]

Dear All,

i want to make a capture template, which will call a function to feed
that template. Is there any way how to do it?

Something like this:

("E" "Dynamic diary entry" entry (file+datetree (concat my-org-files
"diary.org")) <my_template_function>)


I have found that one can use function for _target_, but not for actual
template. Afaik template can be only loaded from a file, right?

thanks
.d.
